Easily fixed, whoever dies last doesn't zone to med bay but instead waits for res. Easy peasy, I didn't even have to think to come to that solution!
Clearly you didn't think at all. In a hard mode flashpoint you can't wait for the wonderfull little rez from the droid, you have to go back, or be rezzed by a player. If everyone is dead and you can't zone in... well hopefully you understand now.
