While playing with friends on the gm_genesis map, when we're in the underground part, skeletons began to appear, but they disappeared after a couple of seconds before they could hit.
these skeletons are added by the addon under which I am writing this.
We didn't come out after that, but the skeletons spawned anyway. skeletons of various kinds, fast, hulk, bloody. gargantua also spawned (1 time). I want to know more about what happened!
