Before new version I had issue with only this line -[DEBUG] HumanNPC plugin is waiting for requirements to be loaded: PathFinding

even if I have pathfinding plugin installed

However when downloading new version i get whole new error in red

Unloaded plugin Human NPC v0.3.50 by Ts3Hosting

ok. the issue was with npcdata file for some reason. Deleted it and now it was working fine for a while, added around 30 new hostile NPCs. Tested them. And after few changes in npcdata file I keep getting [DEBUG] HumanNPC plugin is waiting for requirements to be loaded: PathFinding

if you constantly reload the plugin will you have issues. it is recomended you change your settings with the commands.  if you make an error in the datafile you will get that Failed to initialize plugin 'HumanNPC v0.3.50' (NullReferenceException: Object reference not set to an instance of an object)
