Hey @Stainless
Welcome to our community.
Did this happen in an official server or private server? There’s no admin password to any official server, so the suspicions in this case are probably not correct. There’s been a bug in the past that would cause NPCs to spawn multiple times in the same spot, which with an extra pinch of bad luck could explain your situation. If it happened in a private server, it could very well be your suspicion of an admin just having a whale of a time.
Regarding other claims with admin rights on official servers, they mostly boil down do the use of exploits and gullible people.
