I agree this is frustrating, and i wish they could fix it. I dont think they can/will.

And if a crash/disco just snapshotted and "paused" the crafting, and you reconnected to the same step with the same buffs same counters same cp and same material condition how could people use it to cheat? I mean maybe its possible and im not creative enough to see it, but if it was literally just "paused" until you got back and it then "unpaused" for you to continue then that seems like itd be cheat-proof.
