@OP, I totally understand your position. I need to take a break too. I got frustrated because I couldn't find a swamp crypt, spent hours and hours looking, even an entire weekend searching swamps, and was just moments away from using a map tool when I finally found one. it showed me Bonemass location, ok, great, progress again.
I've now finally traveled ALL THE WAY over to it's general location, to find that the it's spawn swamp is surrounded by large plains biomes on both sides. Frustration has returned. I'm in Iron, and can handle swamp mobs, but I'd prefer an outpost next to the swamp (Mead or BF), not at swamp's water edge. I wish the location rune stones would show all the summon locations (I know there's more than one for them). My frustration level is back up at the moment too, so time to take a break.
