You shouldn't have any problems. If you tell me which mod it is, I can check if it's compatible without any issues. It's currently in the animations/machines development sheet.

This is the mod: https://blackvelvetroom.com/doku/doku.php?id=content:dos:dreamsofsurrender1
And there's a sub-mod for a milking machine: https://blackvelvetroom.com/doku/doku.php?id=content:objects:milkingmachine

You're gonna have to 50/50 your mods folder, what this means is that you take out (temporarely) half of your Mods folder, and relaunch the game, if the error is still there, you know it's in that half, then take the half you know has the faulty mod, and do it again, you'll have to do it until you find the culprit, afterwards, depending if you did the game update or not, you're gonna either wait until your mods are updated (meaning either play Vanilla or do something else), or just go on offline mode in your launcher (if it's possible)

would love actual animations for expressing milk, also could there be a option for how fast milk fills up? and how do you stop a Sime from lactating?

ok so far fantastic mod thank you for working on it but this is what i am working with 
i can start the game with it 
i dont get errors
breasts inflate
i can milk them
i can make milk in bottles and drink/others to drink
i had an issue where i thought the breasts would combust (took a run for the money of katie price 🤣)
the main issue i have though i can do all this but i cannot save it it just freezes my game i have to do a hard shutdown 
but im not getting errors not even off better exceptions 
as soon as i remove the mod all is working fine again and i can save 

i really want to use this mod its got so much value to the game

Hello everyone, first of all, I apologize for the errors. The bug with the sliders resetting is the most aggressive and difficult to catch. I'm focusing all my efforts on finding a definitive solution. The next version might include compatibility with the milk expression machine, and if time allows, custom animations, as that's the hardest thing for me to achieve at the moment. The settings menu will now include the option to change the lactation speed and also the option to stop lactation. I'll be making more progress on the CowSim part and will try to resolve the issue of the resetting sliders and the save game problems as soon as possible.

thank you for this and may i suggest speaking with BaiQing they have the mod cum inflation mod maybe collab with the animations? just a thought as he has the animations good on his deflation 
{my apologies if i overstepped}

I love the mod so far. How quickly should a sim go from drained back to having milk ready? It seems like it's only a few in game hours. Also, any chance you'll have the milk bottles that are created by the lactating sim be readily drinkable rather than having to place them in the fridge first?

There's no problem with your suggestion. I know BaiQing. The issue with the mod isn't so much inflating the body; the problem is injecting the geometry without destroying the Sim's rendering, since the game has limitations inherent to the engine itself. But it should be resolved in the latest version, which is the currently released version. As always, I'll try to resolve any problems that arise as soon as possible.

Then here are your options:

Option 1: go to the Sims 4 folder that has the mods folder in, and delete the following things: localcachethumb(dot)package and the contents of the following folders: cache, cachestr and onlinethumbnailcache (keep the folders. though).

Option 2: This depends on which launcher you use and the launcher must be open. Keep in mind any error on any game you have on any of these launchers that aren't caused by mods can be fixed the same way

EA APP: Go to the app's library, click the 3 dots (...) on The Sims 4's tile, and click Repair.

STEAM: Right-click The Sims 4, then choose Properties, then Install Files and finally, Verify integrity of game files.

EPIC GAMES: Go to the app's library, then click the 3 dots under the game's icon, then Manage, and finally, verify.

Option 3 (this one is Windows only): Open the Windows Security Settings, go to Virus & threat protection and on Protection History. If the exe file TS4_x64(dot)exe has been recently blocked by Windows Defender, click it and select Allow on device. But if you use a third-party Antivirus program, like Avast, AVG or McAffee, add the entire folder of The Sims 4 as an exception.
Option 4: Right-click the OneDrive cloud icon in your taskbar, open settings, and temporarily turn off syncing for the Documents\Electronic Arts folder and finally... right-click the shortcut of the launcher you use and select "Run as administrator".

I saw the option to cook with the milk only once, now i don't see it, i don't see the occult market anywhere and during sex when using the tit sucking context nothing happens. Also i got a Better Exception exception report about this mod.

Este es el mod: https://blackvelvetroom.com/doku/doku.php?id=content:dos:dreamsofsurrender1
Y hay un submod para una máquina de ordeño: https://blackvelvetroom.com/doku/doku.php?id=content:objects:milkingmachine

 

It would be great if it were compatible with this. Right now, it isn't.

I hope you can make it happen.

Best regards!

I'm trying to make the mod compatible with the machines mentioned by the community, but those machines cause an error that prevents the game from closing correctly, interfering with the game's save system. While machines and animations specific to the mod will be available soon, I will do my best to provide support for the mod's machines.

Hi there, here is a German translation of your mod. Feel free to post it on your site again.

 

 

German Translation

 

The only thing I can't seem to get right with the translation program is the mod settings in the Sim menu; they remain in English.

I have seen this question come up but nobody has answered it. Where should we be seeing the occult market option? I've tried the computer, the mailbox and my Sim. If I'm looking in the wrong place, please let me know!

[jrocknyappy]

Hello! Firstly I want to thank you for making this mod. I've been searching for a lactation kink mod for a long time and couldn't find any outside of a few animations. So far, this mod has worked most of the time.

 

I've encountered an issue where I'm sometimes unable to access the settings menu (usually at home), and I've only been able to express milk. Secondly, I can't find any option for someone else to express my sim's milk, though I've seen older posts mentioning it. I also am unable to make anyone drink the milk so far, or cook/bake with it.

 

I think it would be really cool to see this mod use something like magicmelts's drippy milk to further emphasize how close the sim is to being full, and perhaps see usage of milking machines and maybe adding free-use breast feeding.

 

I'm excited to see implementation of animations, and hopefully will see this mod expand more! (like dem titties)

 

Edit: I deleted hucow and the settings and fridge pie menu showed back up, but they continue to sporadically disappear. Also at the moment my sim currently can only express banana flavored 🤔

Just wanted to say something. MISSME and HyperDriver (both inactive animators) have milk machine animations. I prefer the machine Hyperdriver uses for their animations, but the one MISSME uses probably fits better with the Hucow aspect of the mod, so maybe eventually compatibility with those machines can be implemented.

The problem is both of them are banned list on the discord for supports other than missme's patrepon or discord. Also, for hyperdrive one hasn't been updated. Hyperdrive stuffs are banned list on many Sims 4 support discords also.
