1. I cannot turn in missions. They're stuck in pending because the Accept button for the missions' awards are disabled.

2. Now that I have four missions that are stuck in pending, I can no longer accept new missions either, because it tells me that I need to accept the missions in pending first before I can accept a new mission (even though there's room n my mission log). See #1

All of this means that I cannot play my Republic character on Taris because that character cannot accept or turn in missions. The game is unplayable.
