Mmm that's strange.. Is it happening only with proboscis or have you tried placing different animals in the same habitat? Maybe it is an issue with that enclusure?I do have a really weird Problem with the Proboscis Monkey. Everytime when I try to put them in my Zoo, the Game freezes as soon as the Boxes land in the Enclosure. I've already tried it 3 Times and verified the Game Files. It works for some Reason in Sandbox Mode without any Problems
