When the Imperial Tie Defenders respawn for me, they crash my game. They are respawning at Fondor, and this is month 258. I've tried to relaunch the game, restart my computer, and move troops around. I also tried increasing my tech level, but I can not before they respawn due to my save time. I'm really not sure what else to do. This sucks because I was 5+ hours into a fun play through.
