It worked when i first logged in today and now no matter what i do it won't come up again. I've checked my ability binding, and the health regen works just not the shield deployable. When i hit f the device becomes highlighted on the toolbar, but my weapon stays up and if i try to fire, like normal, to put it down i just shoot the gun. Lots 'o' certs spent on this thing for it to be broken.
Servers could still be a bit unreliable. Yesterday I kept losing the ability to throw ammo packs. Did you try changing class then switching back?
Yeah, could still be dodgy server stuff. I can't play as long as it's like it I gotta say, some proper dodgy stuff going down. Changing class then back again might be worth trying. Also, seemingly odd question, but are you moving or standing still when you go to place it?
Happens to me a bit (when you die as you are placing the shield regain) It seems to have to do with item ability cooldown "locking" To fix the issue: Switch to Engineer and throw an Ammo resupply pack. -Yes, it is that simple
