[script I guess] train chop mod
I heard that he can help you sniff out collectibles and stuff like that if you train him, but it's now impossible to train him. I don't know how much of the training was client-side versus server side, so I don't know if this sort of mod is even feasibly possible, but maybe there's files in the game that can be modified so that chop can be fully trained? Is this even a useful feature? I legitimately don't know.
