NRE are actually most often a configuration issue.

Look into exactly when this error starts to appear, and use that to sort out which plugin that is using NpcSpawn is throwing the error, and we can sort out step by step the source and what needs done to resolve this.

More information is helpful like what plugin using this starts or is running, how often it comes up, things of that nature.

the only thing i was using this with before is Dynamic monuments but i have not got around to re-adding that to the server yet.

Is NpcSpawn working properly, including its use by other plugins that use NpcSpawn?

You can make your own ticket any time so others are not getting notifications for a separate issue.

Please try this. If it works great, if you still have issues or questions make a new ticket and I will get back to you there.

foreach (CustomScientistNpc npc in Scientists.Values) if (npc.IsExists()) npc.Kill();

Change to this

foreach (CustomScientistNpc npc in Scientists.Values.ToHashSet()) if (npc.IsExists()) npc.Kill();

In the plugin file.
