I'm in a situation where I get Arniel the Warped Soul Gem from Enthir, but he doesn't give me the next part of the quest to help with the convection. I tried waiting for a few days and coming back to him, but there are no additional dialogue options to continue helping with his research. The only dialogue option is to ask him what he thinks about Ancano. Has anyone else had this happen and then found a way around it? I have saves before starting the quest if necessary. Any suggestions would be appreciated.
what does the quest log say?
and what platform are you on?
edit - here's the known bugs of that quest, per wiki:
In some cases the Warped Soul Gem will get duplicated after heating it. This prevents further dialog with Arniel, thus making it impossible to complete the quest.
An easy fix to this bug is by leaving one of the duplicates of the gem in the dwarven convector. This should allow you to be able to finish the dialouge with Arniel.
Assuming this does not occur on the 4th and final convector heating, the warped soul gem duplication bug can be fixed by putting both soul gems in the next convector box and then heat it with the spell, this will result in one of the soul gems dissapear thus leaving only one to collect and allowing the completion dialogue with Arniel
Another minor bug can occur at the end of the quest. After returning the gem the quest will be completed but if you look at it under completed quests the bullet marker for the last stage is hollow (as if the stage was not completed). This does not seem to affect game play.
The quest may fail to update when heating a convector with the flawed soul gem in it. This may be related to having both Augumented Flames perks. Workaround: place the warped soul gem into a convector, type setstage MGRArniel03 20 in the console, then heat the convector and the quest updates.
