There's a mineral node beside my working mine that apparently has no minerals in it. It keeps demanding an mineralogical survey no matter how many times I complete them, and yields no special ores at all. Still yields all the guaranteed basics but otherwise not so useful. BONUS: there's some weirdness with stocking the pub. The staff will grab a bunch of chicha and try to dump the whole thing into the keg, but the overage teleports outside the building on the ground. Workers will grab it eventually, so it's not THAT bugged, just... that probably shouldn't happen.
