I've noticed over the past few months, don't know the steps to reproduce it, but around the ramp section right before the last room that's filled with borg and 2 crewman, skills periodically stop working. The movement keys work fine but not the skill functions, hence no shooting or abilities can be done (makes it hard to go after Rebecca ).

I usually have to correct it by doing a disconnect, and jumping back in hoping it puts me back into the mission when I log back in. Usually it does, and all skills are working fine again.

Last night it happened to a fleet mate during a private infected normal. Hence he could not do the disconnect work around. We tried remapping his keys, killing him, respawning.... nothing worked. We finally had to give up, and once he beamed out of the map area, his skills were working again.

Like I said, it's happened during that one section of infected, can't really tell you which buttons were being pushed to reproduce it. Just wanted to give you a heads up on the defect.

It's not just on Infected. It happens at random times on any given mission, so it's nothing you've done. Who knows if and when or how Cryptic plans to fix this. Looks like they're not interested in fixing things, just making it look pretty for F2Pers.
