I don't know why and how it happened! but i can tell that my AI teammate try to go down on a ladder and bug (no freeze, head still look at me as if I was the dumb!)

I try many oder : saying "yes sir", doing nothing!
I shoot his leg : saying something, doing nothing...
I give an order : moving a leg, and... Flying.
I give the order to drop his bag, he did it but not a move...
Oder to pick his bag up: doing nothing!... {F23832} {F23833} {F23834} {F23835}
