Siege at Fort Firemoth wont start

[Maxrebo]

I have complete pretty much all of Morrowind except for the Great Houses,Siege at Fort Firemoth and Tamriel Rebuilt.When trying to do Siege at Fort Firemoth I've encountered a problem.Selus Gravius won't ask you to do the quest nor will he even give the topic about Fort Firemoth.How do I fix this issue.

Here is my mod list in its load order.

I am also thinking of ditching Living Cities of Vvardenfell since it can be a real pain sometimes,what do you guys thing.Plus have any you guys tried out the new Skyrim UI Overhaul mod for morrowind, if so what do you think of it.

Not to necropost but I got this quest to work by using the interior version of the mod.I still have no clue what mod was conflicting with it it that prevented the topic that starts the quest from coming up but,I guess that doesn't matter anymore.
