Do More Harm - Niles Stuck

[bringtheparty]

I am playing the quest "Do More Harm." Niles is suppose to produce Niles' Extra-Strength Explosive Gel, but he is stuck and won't move.

I have waited so long that I can't reload a previous save without losing 6+ hours of gameplay.

Is there a way to get him unstuck? If you are unaware of this mission you also can't go back, teleport or leave this area. My ONLY hope would be to kill Zebulon Tran, but that would also make me lose Niles and I'd rather not do that.
