I pick up the 6 daily writs, i complete them, I take the wayshrine to orsinium. I arrive in front of the fighter's guild/bank. I ride to the edge of town to turn them in.
If I ride back to the wayshrine in front of the bank, the game is almost guaranteed to crash.
I have to ride to the wayshrine in Shatul.
Turning in quests or writs in Orsinium makes the game crash if you try to use the wayshrine in from of the fighter's guild/bank.
