This package is all of the Imperial Legion quests. There are definitely still some quirks and issues around the game that cause snags in the quests. I'll list them here as I remember them:

Gnisis Widow and Eggmine -
 Since quest dialogs aren't active if the quest never starts, the guard has nothing to say to you about entering the locked eggmine. So I started the Eggmine quest to 1 at start of your game but moved Darius' quest to stage 2 so there won't be a quest when you start a new game. This also helps if you never join the legion but need to enter for the Mage Guild quest.
 Second issue is with the Queen. Right now all of the creatures fight each other and so she will probably be dead the first time you enter. This breaks the Eggmine quest but it still gets completed, you just don't get credit. This will get fixed once somebody fixes all the creatures that fight each other.

Rescue Ragash -
 I still can't get her to follow you. The quest prior (rescue pilgrim) works fine and it does the same function. Maybe another set of eyes can see what I am doing wrong.

Talos Cult -
 I set both cult soldiers to StartCombat() with the player but maybe the problem is this code is tied to Darius' dialog about killing them. I guess you can't do this command across cells.

Rescue Joncis -
 The daedric door to get to him has no animation to open it. All loot is flagged as stolen. Should this area be flagged as Public? Should this be done to all daedric shrines?

Rescue Dandsa -
 Like Ragash, she won't move.

Suryn Slander -
 You get a bounty for killing him. I have a short script to drop his relationship with you everytime you talk to him but he never seems to attack you.

Protect Saprius Entius -
 This is a mixed bag of strangeness. He won't follow you, but when I fast travel to Ebonheart, he was there and followed me half way across towards the inn. He stopped and won't go further. No other guards walk the whole bridge which makes me think there is a mesh problem here.

Lord's Mail -
 I had a guard in the chapel with me. Since the secret door needs to be picked, this makes it hard if you aren't a good thief. Also, everything in the room (muck included) is flagged as stolen.

Other follower quests, Jocien and Madura work just fine as followers (well, Jocien doesn't follow you, it is Assaba, but you know what I mean).
