Yeah its pve because it lets me use it in story missions etc. Its ones I crafted. Its the Prototype Polybiotic Med Unit. Like just now about 20 minutes ago I used it on a (not sure what they are called in SWTOR, elite mob? Bright gold star?) and have not been able to use them since in other fights. But if I zone to my ship and come back, they are back again.
They are grayed out in my bags an on my bar. Its keybound as well.
I just figured it was a bug all these years thats still never fixed.
