After unlocking the black hole/getting acid rain, all the haulers decided to take the day off for some reason, took more than quarter of an hour for them to fix themselves - think it said they were looking for pebbles? (also just got the belt), as the belt dumped it into the pit it's like they were trying to pick up the pebbles that were being pulled into the abyss

Mid game was very stone starved, can't make them focus on the rocks to collect and miners often walk a lot for one last pixel they missed. Be good to expand the belt to the other resources also
