Expanded Incest Mod

[The_Countess]

Update, false alarm, I made these Sims while half asleep and forgot to make them related

[The_Countess]

So actual bug??? My sim is pregnant to his brother but I can't reveal incestuous pregnancy, the interaction just isn't there

If you just gave it to them, that's intended. It doesn't depend on friendship, but on a hidden relationship track. You have to perform more persuasive interactions to unlock more stuff little by little. First non-touching romance, then touching then sex at which points the persuasion stuff goes away. Some friendly interactions that have the persuasion icon raise the hidden reltrack too, as well as romance when it is unlocked. If you don't wanna got through all that, you can give them the incest trait manually

After trying to persuade the other sim for some time, my ability to use persuasion went away for the same two sims I previously had the option for.

will you take over the forbidden fruit mod now that its been abandoned? it would be great if someone did

Is the mod interactions restricted to just adults or can teenagers use them as well?

I cant seem to get it to work at all, I added the pie menu trait to each sim and the only thing I can do is repeatedly ask their opinion on it and enable discovery. Tried to remove the mod and then re add it but that didnt fix it

[redreaper]

I have sims version 1.121.137.1020 and your mod's version 1.2.1, and it doesn't work, it kicks me out to the world map

Hey are you gonna give up on this mod too?

What specifically are you expecting to see that you aren't seeing? Things are showing up fine for me. Romantic interactions from the mod usually have relationship and social context requirements, they don't show up immediately. Both sims need the incest trait from the unlocker

The game hasn't even received a patch since the last time I was here

Teenagers can use them, but only with other teens

Copy pasted, since your game is updated ignore the game version part:

Since this is not an error that I have been able to replicate in my own testing, it means that a difference between our games is likely causing the error. This can be caused by outdated games, mods, or if any of those are accounted for an incompatibily I might have overlooked.

Please check: 

-That your game is fully updated to the latest version. Anything below 1.121.342.1030 is 100% incompatible given I added tests for new relbits.
-That your other mods are fully updated as well. This seems to be a very common cause of error people have reported. Outdated scripts can make other script mods break, even if your game didn't break previously. Hence, any script mods are more likely to be the cause for something like this. 

-That it doesn't happen if your remove the mod.
-That you have all the specified required mods in your game and that they are updated. For example: Lot 51 core library, Wicked Whims, and Inappropiate unlock for Expanded Incest
-That you have all the required DLC for things like the clones add-on that require them

-That the mod is correctly installed: scripts can be no more than one folder deep. Including the one in the Clones add-on subfolder

 

To check whether it's another outdated mod or a potential incompatibility with one of them: test my mod by itself by renaming your mods folder Mods1, and making a new folder called Mods with just the mod you want to test. Don't forget to copy over the Resource.cfg file and any other required mods as well, as well as MC/BE if it has an exception. Run the game. Once tested, delete the new folder you made, and rename the original one to Mods again.

-If the error doesn't persist with the mod by itself, you can employ the 50/50 method to narrow down the potential cause. Start with more likely targets such as mods that affect the gameplay itself, rather than cc.

-If it does persist and you have checked all other things mentioned, here's the information that can help me try to narrow down any potential incompatibility more easily when you report it:  Your game version, any last exception files you have gotten, attached if possible, The DLC on your game (skip kits), the mods you have on ypur game (this can be a lot, but consider it a last resort. MC/BE last exception files list them for you, though), and importantly, the things you have checked so far, and any details surrounding how the error was triggered and the error itself. The more specific, the better.

I have the newly updated download and am also still getting sims who are in no way related getting options as if they were. It's hit or miss as to witch couples do though. I drove myself crazy (before I decided to check here and realized you had tried to fix the issue) with one couple because they are my most wholesome couple, trying to figure out my issue, thinking it was something I messed up on the characters. I even made a twin of my sim and hooked her up with a completely different safe guy on a different save and she ALWAYS triggers the incest options no matter with who or what I change on her. Like she is related to the world. But I have other couples that don't trigger it, even though they have just as much friendship and romance with their partners.

Oh, Tessavale's comment reminded me, I had a similar problem where a mother would have the option to kiss her son and it would say "Kiss while telling him how much you love him as a Dad", and when their relationship was exposed a lot of the hate mail directed at her also said "Dad" instead of "Son". 

 

I appreciate how active you are with trying to fix the errors people find, keep up the good work!

Thank you both, updated it for that

Is this going to be fixed or is it by design now?

Update the mod please...

I have tested the patch with just my mod and WW and haven't found an issue so far. What issue specifically have you found after the patch that you believe needs to be updated?

[teepea81]

Thank you! But I wasn't really planning to, I meant that just because I don't answer immediately, doesn't mean I'm abandoning it 😅

I do wonder something. Is it possible to add some kind of research option. You know. researching incest online and making a Sim more open to it by researching it. Kind of like a self discovery thing.

[Howdy65]

The basic interactions seem to be working, but nothing happens when I click on "add incest-related trait."

Hello...
will this mod conflict with "ForbiddenFruit" mod.?
