I've turned the unlimited special on or off and when I try to use a grenade the mercs go thru the motion but no object is thrown. Fashbangs the same. I tried restarting without trainer and same issue. Anyone have this issue?
You can try to reinstal de game. maybe an error when instaling the game. Or try to see the integrety of the game cache on steam library then game properties then local files. steam will scan the game for errors and correct them. if this not work go for option 1
