To "activate" a voidvial, it takes 100s in the primordial voidforge, and it has 1% chance to get a ruptured result instead, which has a 30s spoil time to result into an atomic explosion.
I guess the design intention is to deal that with that by the "safe unshaped void disposal" recipe. However, the spoilage seems to start from the time when crafting BEGINS, not when it ends. So if the 1% lottery is hit, the detonation will immediately happen.
And this is not rescuable by quality as well: even a legendary primordial voidforge still take 40s to finish the craft.
Is this intended?
