Okay so this is not a new glitch but this is my first time experiencing it. At this point in the quest Arniel's Endeavor you have to take a Warped Soul gem to 3 Dwarven Convectors and heat them using the spell Arniel's Convection.

I went to the storeroom in Mzulft and heated it like i usually do in other files. One handed for 3 seconds and the mission prompts me to place it in a final convector already. I found that odd but didn't really think twice about it (foolish i know). So from there i kill time with a couple of other quests and go to finish it off at the convector near Shor's Stone and nothing happened. I flame the crap out of it with the correct spell and no prompt.

The quest does not prompt when placing the gem in the convector nor does it want to complete when going to other convectors which i have done. I went to 2 more out in Markarth and nothing. Apparently this is one of those glitches that have been around since last year, no surprise there. Hopefully someone has found a way around this if not...someone should get around to fixing that...

I am at the current update version 1.8
