PC Atlantis

I have progressed to the Death Hall in the mod. My progress is stopped by the pile of rocks that seemingly will not budge. I have watched a walkthrough and my game is different. In the walk through there are no rocks blocking the way. Just the hall's challenges to overcome.
Anyone have any experience with this mod?

None at all, unfortunately. You may try the site where you got the mod, scroll through the comments and see if others reported a similar problem.

From general issues with Skyrim, though, it almost sounds like what they do to dungeons in case you discover them before getting the quest. Maybe something's happening to prevent the dungeon itself from realizing you're there on the quest, so the way isn't open? You could try to find the quest ID and stages assigned by the mod author and use the setstage command in console.

Thank you Joe. I got out of that Hall by using my Whirlwind Sprint Shout. Not the prescribed way per the walkthrough but it worked. Now I am supposed to go up a ramp dodging large boulders rolling down at me.
Trouble is, the boulders don't roll, they are static and blocking the ramp. Tsk tsk. Haven't solved that issue yet.

Solved that glitch by backtracking saves and playing them forward until I got a scenario where the rocks did as planned.

I'm sorry, I didn't realize you were stuck inside. With a PC, you can always use your coc or cow commands to get out. COC = center on cell and COW = center on world
The world one is a bit harder to use, if you don't remember the coordinates, but you could say cow tamriel 10, -1 and it would plant you wherever 10, -1 is (I THINK it's outside Whiterun, on the Pale border.)

COC is a little easier to use. Open console and type help and the name of wherever you want to go. ( help breezehome ) or some other interior cell. Scroll through the list until you see the name and the CELL label, and use the system name. So if I live at Breezehome and wanted to go home, I could open console and type coc whiterunbreezehome or however it's listed in the console, and just appear there.

Got that mod finished. It was entertaining and a bit challenging at times. Thank you all for the help.
