Using the treasury, and opening the guild pane (G key) seems to cause a funky crash/stall.
Not sure if this has been reported or not, and i’m not entirely sure if this is the exact step to cause it.
The only certainty i have is
1) I Interacted with the treasury npc
2) I opened the guild panel
3) I tried to leave the guild hall using the button on the panel (without closing the treasury window)
4) The client locked up at this point.
