Set thrall city spawns bugged

Game mode: [Online | unofficial server]
Problem: [Crash | Bug | Performance | Misc]
Region: [Uk]

[So all of the thrall spawns in set city are spawning triple thralls on the same place holder this is causeing some serious lag we have tried to restart the server but that hasn’t helped… we have cleared the whole city and that appears to just make things worse… is this a known issue or does anyone have a way to fix this?]
