thats normal . the game crashes because a quest window cannot open . notice when you move around to places like varanas a quest window opens , well when you crash and then you log back in , presto ! that quest window that couldnt open is now open .
dont reload the game , dont try weird gimmicks there is nothing wrong with your machine .keeps the scriptors and the bots down . why fix what works . when you get to an area where a window is going to open log out then back in the quest window will be there and you wont crash . yes its a flaw . accidently on purpose maybe lol ...
