Testing this mod on the Center. Spawns everywhere are uncommon or rare save for the swamp which is currently overrun with dragons. From north end of swamp to half way through 16 toxics, 8 venom Pygmys. It's not an issue with your mod, but it an issue with the Center map itself. I say this because we also have dragon gods and I found 3 blackhearts, 2 fire dragos and 2 cryos and 2 Valkyries. So it's the spawners in the swamp on the center that causes over spawning. This is probably why modders cannot seem to figure out how to stop it from happening resulting in them removing swamp spawns from their mods all together (eg. Monster Ark and Seven's Legendarys) We're probably just gonna try turning Toxic dragons and venom pygmy spawns WAY down to see if that help. otherwise, we'll come up with an alternative spawn location and kill spawns in the swamp if that's possible. Just wanted to give you a heads up on this mod working on the center map. The patterns on these guys are absolutely beautiful.
