Hi,
my animal handlers are producing errors every few seconds (probably every time they actually want to train some animals and not doing other stuff)

Esception is pasted here https://pastebin.pl/view/9290e590

I am not sure if using mods that remove tameness decay (Mad Sklls) or specific food items used for handling might cause this error in "[TKey,TValue].get_Item".
My modlist is currently at 598 active mods but if it helps i can post the list too.
