There are two points in the game where a blocked passageway is cleared later for you to enter. The first in Morrowind is in the cave of Dubdilla where entry to the Daedra is blocked until you are doing the 'cure for vampirism' quest. The second, in Tribunal, is in the Temple sewers before you are asked to find Brazilar's mazed band. In both cases with a little ingenuity you can get through the barrier before the blockage is removed.

For Tribunal it probably means nothing as you will be doing that quest as part of the game. However for those of you who do not become vampires, don't give up on Dubdilla. There is some loot higher up in that sealed room!

And you don't need to cheat with the console to do it.

So enlighten us!

Well, I thought it was clear. You just keep trying to get through. In the end you will. In Tribunal the rubble disappeared from behind me but not in Dubdilla.

So, where's the cheat you mentioned, hmm?

I think he means keep trying to jump through, and eventually you'll cause a collision glitch and phase through the rock. Am I right?

I think you've right swith and i hate that bug. Cant bethesda make a patch that prevents that bug

I found the Dubdilla cheat by accident. I went there before I knew about being able to play as a vampire and was sure there was meant to be a way through so as Switch observes I kept jumping to try to find where I was going wrong. I didn't even realise it was a cheat until I found out later about Vampires and that it was part of a quest. The Mournhold one I tried to see if it worked there and found it did. However I don't use the cheats, I'm just inquisitive.

And i hape camed upon a almost same bug just when i played, and it happened to me serveral times. When i were jumping around on the roads of vivec and i saved when i was in the air on quicksave and when i were about to land on the road i just fell right trough it. And that happened to me serveral times and not only when i saved in the air it happened to me when i just jumped. --Strange--
