This game really needs more stuff that can just screw you sometimes. Waisting a few turns because a dig site collapses is nothing. I say when something like a dig site collapses it should make you regret ever digging >:D
Well, spend less turns to lower the turn loss is one way to feel better about that I guess. I don`t find irritating and it should be like that and not a perfect world where you always get what you want.
Is a minor irritant.. tho in my case on rare i have to use 9 else i dont find anything.. and wastin 20% of that batch on a bunch of spores is irritating lol
