I guess this means I get to welcome you to the forums.

Hello, blakeredfield!
Regarding your problem... I'm not sure how much help I could be but the game sometimes crashed that way for me on Tatooine and Manaan after I had found all five Star Maps. (not to mention the usual "restart every 20 minutes and face corrupted saves...") I'm sorry, but I don't know of any other solution other than solving that quest before finding the last Star Map.

Perhaps just load back to the last save before finding it... even though it might be a drag, depending on how much you've done since then...
If, however, you haven't found them all yet, I'm very sorry but I have no idea and that means I'm just meaninglessly rambling here, so...

Hope you find a solution.
