I hate to add another bug here, but I've found a small problem with the stage of this quest in which you are asked to eliminate the Dwarven spectre in Jeanne's house. Immediately after your journal is updated by your conversation with Jeanne, she attacks the Ordinator in her shop. I've been able to replicate this all three times I attempted to, and it happens even when no mods are active but Oblivion.ESM and Morro_Ob.ESM.
You can test this by using these script commands
"COC VivecVSJeanneXSTrader" Will take you to her shop.
"setstage fbmwEBBone 60" will allow you to speak to her to progress the stage. If she assaults the ordinator after ending the conversation, then this is not my personal problem.
the official UESP wiki page for this quest can be found here: http://www.uesp.net/wiki/Morrowind:The_Dwemer%27s_Bone

I was unable to reproduce this, however while testing I noticed some NPC behavior which I don't quite like. I'll post a fix later.
