recently i got dishonered from gaming with gold and i've been enjoying it.

right now i'm in the mission where i've been betrayed and i had to reclaim my weapons.

eveytime i kill doud my game freezes.

is this a known issue or am i suppost to let doud live?

Never heard of this error before, strange. But yeah, you can let Daud live, just sneak close to him, take his keys and leave.
