At some point a bug was introduced in which mass crafting just randomly stops. This WA creates a flash on your screen each time you craft- if the flashing stops, know to tab over and restart it.
Green flashes are if you have Aerated Phial of Quick Hands active.
Red flashes are if you don't.
It's not supposed to load if you're outside of the capital, but idk, maybe it does. That'd suck.
This one in particular has a load condition for the alchemy buff, but you can trim that off if you're doing something else.
