PC Predator crouch rebind issues

Sometimes the predator will crouch on ground other times it will not work in game. Helps to be silent without using the absurd stealth and ridiculous noise u make

there are 2 crouch buttons i have found, i rebind crouch to L-CTRL but then when in the trees i must still use C. I think the 2 sometimes get confused.

Sometimes buttons just don’t work. Both pred and ft I have issues with attack not working, leap, etc

i did that changed to berserk and it didn’t work even though mapping are correct.

changing classes seems to effect the binds
