Lately I have been noticing my linkgun not working correctly after I die and come back in a new wave. It shoots slower and won't let me link, but if I switch weapons then go back to link it works fine.
I noticed this happen a couple of times in the past, but last night it was consistently happening.
I guess I should quit dying.
Do you use an auto fire toggle at all? I've seen similar behavour if you have fire pressed when you spawn.
Example, I often find when i spawn the flack is stuck lobbing grenades until i switch off it.
