For some reason the research is in a Big and Small tab, even without Big and Small installed

@Gula
That is most likely the case. Ludeon changes trainability of the animal when the catalyst is used.

Probably some mod is caching the trainability or otherwise doesn't correctly handle the trainability changing.

Which would explain why it happens with or without this mod.

@McDuffie
I would be surprised if actual errors are Ludeon's fault. It is likely another mod.

The issue with pen animals is on Ludeon though.

@Gula same issue, I was using them fine yesterday but cannot today. Will add this mod once Ludeon irons the item's issues out.

I actually have the base game and I dont have this mod installed, yet when I go to use the catalyst my UI disappears as well. I wonder if theres a bug with the current implementation of catalyst or it might be another mod causing the issue that Fenc reported.

@AnotherAbyss, Holgast, Cake Sparkle
It technically should, I'm quite certain that is a bug that slipped by Ludeon's testing, so I've reported it to Ludeon.

I'm going to wait and see if they will fix it before trying to hack into their code to fix it myself.

@Fenc, JonesXVS
Not seeing that issue here. Please provides logs. It is most likely a mod conflict.

Agree with the other guys, i had assumed it would remove the pen requirement. Would be great if you know how (and want) to add that.

agreed, would like it so that the sentience catalyst removes the pen requirement for pen animals

anyway you can make animals that need pins, like horses, no longer need pins?

made one and i cant use it, ui dissapears

this removed trainability from my monitor lizard and also prevented me from using any sentience catalysts on him
