At the request of several forum members (shunter being the last). I am officially getting off my butt to create a list to flag these plugins. However, I will need your help. While I do use quite a few mods myself, no one can possibly install and use all of the stuff that is out there. I specifically do not ever use any clothing or armor mods - well at least not the esm\esp files that come with them anyway, as I make my own esp armor\clothing files so I know that there are no conflicts. I realize that many lack the knowledge to do this so please volunteer any mod that you have had cause conflicts in your games.
General Note (by Symon): "I'd add a note to be careful with ANY mod that adds animations and uses PickIdle rather than PlayIdle."
Sexlivion - this "may" be compatible with the core systems of lovers but plugins like RaperS (with chaos mode turned on) and Joburg\LandE can cause CTD's. Lovers Stupid also may cause this when used.
Friends & Lovers
Dynamic Foot Position - this has been reported to cause crashes when engaging in sex both on this forum and over at hongfire.
Immoral Sisters is incompatible with - The Gold Crest - A Major Pirate Quest and Unique Landscapes - Bravil Barrowfields. There are some rather offensive terrain tears in one and the sister’s campsite outside Bravil is almost totally buried in both.
Claudia's Little Secret - currently CLS does not work with lovers with PK. A patch is being worked on but no eta has been given.
Mayu's Animation Overhaul.esp - this mod causes Lovers animations to stop playing. It also conflicts with other mods that have or rely on special idle animations.
Vim & Vigor Overhauled - when using PK Extender this plugin interferes with stamina and can lead to the death of NPC's when they have sex.
Death overhaul and resurrection - it searches for the knocked state, like when lpk animations end. Sex causes death with this mod.
Suspected Conflicts or just Unfriendly
Companion Share and Recruit <--double face bug happens as well as other oddities at times.
Estrus v19.5 - You need to turn off the NudeShy feature or it over-rides sex animations.
LoversDoctor - This causes conflicts with TamagoClub if used together with it.
CursedArmor - It will work but you have to load the ESPs after Lovers but before bash patch and go into the CS and convert all the armors to use the amulet slot instead of the armor slot. It "may" also conflict with other plugins so be aware that you are taking a bit of a risk here.
Kvatch Rebuilt - may have issues with lovers bitch
Sexy Maid of Chorrol - you can't have sex with the maids while the custom animations are playing. You can rape them if re-enable them to be eligible for sex via the settings (they are marked disabled by default). Not sure if consensual sex is possible with them.
Tantrivaylia - is not compatible with HiyokoClub. A CTD occurs whenever progeny are present in the same room.
Colourwheels overhaul plugins and\or the Sexy Imperial Legion Extended plugin - I had a small issue with one quest stage in Bravil Underground that I "think" was caused due to the swap out of the bodyguard. The work around was to manually advance the quest via the console.
Lovers Rape Struggle - does not seem to get along well with rev96 of LPK. Certainly doesn't get along well with the latest version of PK Extender.
Post anything you guys have found and I will keep the OP updated.
