[1.0.1945] Cannot open Animal or wildlife tab

[Grug]

The console instead spits out an error quite rapidly if I try

It might be my savegame-I noticed if I make a new game or look at a past auto-save I don't run into the issue. Is it possible for me to fix the savegame?

[Ralpf]

I have the same bug, but it is only my animal tab. My console shows what looks to be identical errors.

I have a save made on version 1.0.1943, it's animal tab works on load.
