Finally noticed and am trying your vampire and alien overhauls and loving them.. but I am currently wondering if something may have changed with the Lot51 core library in relation to your vampire and alien overhauls.
In the log for the Lot51 core I get numerous warnings about the same thing - "This affordance does not use flexible_content basic_content" I'll share a few examples here showing these warnings coming up in the lot51_core.log for both mods.
I would ignore these warnings in the log, but from what I can tell the actions aren't firing as a result of not being processed by the current Lot51 core library (3.91 released February 16, 2026):
3 Examples from the Vampire overhaul:
[WARNING] Cannot inject conditional_actions to <class 'sims4.tuning.instances.mixer_social_Fight_targeted_mean_VampireAndSim_Duel_WithoutGarlic'>. This affordance does not use flexible_content basic_content.
[WARNING] Cannot inject conditional_actions to <class 'sims4.tuning.instances.Kayaker: mixer_Vampire_TeenSlayer_VampireDuel'>. This affordance does not use flexible_content basic_content.
[WARNING] Cannot inject conditional_actions to <class 'sims4.tuning.instances.Kayaker: mixer_Vampire_TeenSlayer_VampireSlay'>. This affordance does not use flexible_content basic_content.
3 examples from the Alien overhaul:
[WARNING] Cannot inject conditional_actions to <class 'sims4.tuning.instances.Kayaker: AlienAbility_Command_Wander'>. This affordance does not use flexible_content basic_content.
[WARNING] Cannot inject conditional_actions to <class 'sims4.tuning.instances.Kayaker: AlienAbility_Command_Begone'>. This affordance does not use flexible_content basic_content.
[WARNING] Cannot inject conditional_actions to <class 'sims4.tuning.instances.Kayaker: social_Alien_MemoryErase'>. This affordance does not use flexible_content.
If this is all normal sorry to take up yourt time. I asked on the Lot51 support chat and the lot51_core.log came up clean when scanned by the bot but a moderator agreed those warnings may indicate that certian parts of both mods may not be being processed by the Lot51 core.
Also running your cowplant overhaul mod and no similar warnings for that one re lot51 core.
