I have noticed a cave system on Isle 3 in which one exit is behind a waterfall and the other on a cliff facing the ocean. I'm not sure if it's a bad server setting or something else but the caves cause anyone nearing that section of the island to get 10-15 FPS (when previously getting 45-65) due to it having well over 100 active spawns of Araneo, as well as another 100 active spawns of Bats. I also noticed a floating particle with a Skull and Crossbones logo turned sideways as if it's a spawner target.

Anyways as for the question: Is a server setting broken and I have more spawns than intended on accident, is this an unfinished area that was forgotten about, or is OP a fåggot asking about a secret dungeon?
