For some reason my medic gun just decided to not work. I hold the trigger and nothing happens, not even the green beam. Unsure if same reason, but just half an hour ago I had to restart the game because my bullets stopped registering.
The medic gun issue happens quite often. Just quick-switch to another weapon (1-4), and then back to the medic gun. Fixes it every time for me. I havent ever had my bullets not register though.
I just started trying out the medic... stopped again, because i constantly had the heal gun stop working, and changing weapons didn't work. I had to go to a terminal, switch class and back again, to make it work. So something's not right.
I have had a few bugs like this happen. Normally I find that reloading the class at a terminal helps with whatever the problem is. When ever the medgun stops working for me, I will no longer be able to resupply from ammo packs either. I think its something that keeps you from interacting with the world. I know this bug was still in beta, but a lot more common and would even keep you from using grav lifts
