Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Beta Black Cove - game crash on reentering

I did not complete all possible quests during my first play through in the Black Cove - I missed the hidden button that allows for finding the key to black gate.
That means I left with bunch of stuff to do in this zone.
Now, every time I try to enter again - my game crashes.
(doesn't matter if i try to reenter from the beach side or through the waypoint).
