I'm thinking that adding in more woes to the game is very definitely a good idea (they do get a bit stale when you start seeing the same ones repeat often enough), but refining each group of them is important too, so this sort of thread is a good idea.
I cant comment too much on specific ones just yet, as I cant think of any that really are like super messed up or anything. Though there are some that seem very situational, to where if they appear outside of certain situations, they effectively dont do anything. Like that "collapse" one, I think it's called, the ones that makes mountains into hills and other stuff into.... other stuff. I've had that one show up, but.... not have really much effect. It's not that it didn't have alot of tiles to mess with, because it did, it's that messing with them simply didn't alter anything. Terrain differences never seem to have enough overall effect on things as it is (not in my experience anyway), so this one just doesnt seem to do much.
