Just encountered same issue as Bereskarn - none of the cutscenes on Dxun would trigger, which, I think, caused bunch of other minor bugs - friendly animals, unable to interact with panel on the crashed ship or the droids, Zhung dialogue not triggering. Removing 401DXN.mod fixed it all.
Seems another person on steam forums had the same issue - http://steamcommunity.com/app/208580/discussions/0/530646080867117981/ - his video pretty much shows what happened to me.
Hope you can find the problem. I love the mod and will definitely keep using it, aside from those two faulty .mod files.
Great mod otherwise though. You just need to remove the 401dxn.mod and 702kor.mod files from the module folder after installing, but otherwise it works well. Cheers.
This mod is completely broken at some parts, specifically the 401DXN and 702KOR modules. At 702KOR (The Korriban Academy), it prevents the cutscene from playing when you enter the area, causing Darth Sion and the two Sith Assassins standing next to him to not move from that spot, or trigger the scripts for that area, essentially trapping you in it unless you load an earlier save and remove 702KOR.mod from your module folder. Same with 401DXN, but there it isn't game-breaking because there's nothing preventing progress from that zone, as the exits aren't locked.
