Sneak makes the game crash

[Slave35]

If I sneak near a human merchant as an iksar monk, then attempt to buy something... the game crashes.

I believe this is because they turn to look at me and are no longer able to sell me anything since the faction goes back down. I'm still in the merchant menu even though the faction has reset. I tried to buy backpacks from Ponila Quickfingers twice in East Commons and both times got booted out of the game.
