nvm… its a mod. gawd, I feel dumb now
Sounds like a similar bug that plagues armor benches. If you queue up multiple pieces of armor and the padding has to craft along with it, and you remove one of the crafted pieces before it’s done, it will delete everything but the padding in the queue.
yeah, I’ve noticed similar… at least in that case, it’ll keep running if you’re patient and don’t touch anything. 
Patience is tough when you’re crafting a set of eldarium armor on the garrison bench. 
I didn’t think you needed to use fuel at the casting table, or the blacksmith’s bench - I’ve been using them with out any type of fuel for quite a while. Does using fuel cause the bench to go faster?
No, fuel is not burned in those. I assume they’re pulling out crafted items.
