Starfall crater crash, disconnect from server unable to enter enstance

it's a T16 Maze map, which the game disconnects after entering starfall crater. then i can't even enter the game. when i log-in it saids unable to connect to instance. i have to swap to a different server. after i log in, and tried to enter the map again through the portal. the game crash again. this is so rage inducing. it's quite rare to see a starfall crater.
