When setting up the bonus tiles, what do you do if you get one at the start of stage 2 or 3 that requires a certain number of workers in the mine? There would be 0 workers because the mine has just reset.
If you follow the rules, the bonus tile for the following round is executed before you clear the mine, not after. Take a close look on the player aid. First you advance round marker, then remove quests, then execute bonus actions, then you do the end of stage stuff (clearing mine, refreshing market/quest etc.).
