In the quest: Scoundrel's Folly (part of the Thieves guild questline), the person Golum-Ei dissappears as soon as I enter the brinewater grotto...
He gets stuck in a wall at the far end of the grotto.
I've google'd this problem, and it seems a lot of people are having this game breaking bug.
There are a few ways to fix this problem, and I've tried them all, but none works.
And now it seems, that I can't finish the Thieves Guild questline in any way whatsoever.

I'm having this bug since January, and I've been waiting since patch 1.3 for a patch that would fix this game breaking bug.
I'm lvl 73 at the moment and I don't want to start a new character right now just to finish the Thieves Guild questline...
If you use the search this quest on this forum using the top-right search bar, you'll see that A LOT of people are experiencing this problem!!!

I hoped Bethesda would fix this bug in patch 1.6, but they didn't...
Maybe if more people go complaining about this bug, Bethesda understands that they need to FIX THIS QUEST..


So if anyone else is experiencing this problem, please comment below and let's hope Bethesda would fix this in patch 1.7!!!
