Last two days Ive had a weird issue with the repairgun as Hotwire.
Say Im healing the war factory, a Nod guy enters and I pull my pistol out, shoot him and then press 7 to go back to my repair gun. Now when I click fire, nothing happens, the ray isn't visible and Im not affecting the building. Ive tried switching weapons both with the scroll wheel and keys - still same thing.
What I have to do is to resupply at a terminal to get it all working again.
This only happens sometimes, not very often, but it's annoying
ALSO: If I press E at an enemy (Nod at least) Purchase terminal I get an error saying "You cannot use this PT" but my ammo is still getting refilled :P
