So, I guess the first item in my "Tool" bar during a mission keeps choosing itself. Like, if I were to put a health capsule there, it would keep on trying to use it even though I'm not pressing anything. And its not my keyboard, I changed the hotkey for it 5 times and the same result keeps happening. Yeah, not really sure what to do here.

And, yea, I restarted the client.

Sincerely,
Riamu the Knight.
