I have had this problem for a while, just never thought about addressing it. After a decent amount of game play the game wont let me use repair kits. It makes getting the platinum trophy very difficult and i dont know if it is a system set in place in the game or not. Does this happen to anyone else?

 

Do you have any TECH equipped that disables healing? I had one on Grimlock for the longest time and it confused the hell out of me.

 

I dont think so, honestly i havent played the game in so long i dont remember but i will check.
