Hi, I'm having the null exception the same as the person above - Tried a few fixes myself.
1. Tried unistalling and reinstalling the game with a complete clean wipe
2. Installed only the mods for 0-creature pack animals for A19, creaturepack mechs for A19, Creature pack humans for A19, Creature Pack Zombies from A19 with CharacterEffectsPack for A19.
3. Still have the issue. I also deleted all my old saves, just those mods, and still happening.
4. yes, this log has the other mods in it too, but it was throwing the errors either way.
posting my log in pieces as it's too big for parsing easily - please fix this - i love this mod and the cool zombies. Creature Pack Mechs and Animals is working fine though^^
Posting it in replies after this post.

OH, and I also tried a new game save. Just so you know. So it's not a corrupt save
