It’s a huge negative on QoL that smelting or bolting a bunch of ore or cloth, or mixing potions, or prospecting or milling or whatever - take so, so long. Several times over the past few months I’ve just left the game running while smelting a huge pile of ore or bolting a metric heiny-load of netherweave and went to bed.
I’d like this to be better, and I can’t be alone on that. No it’s not a huge priority of course, just something nice to make life in game a little better.
