Version 2.1.3 won't load NPCs

Everything was great with 2.1.2 and then I upgraded to 2.1.3. Now when the plugin loads, it ends with "NullReferenceException: Object reference not set to an instance of an object", and the NPCs fail to load at any of the monuments or anywhere else that are specified in the data files. Assistance would be immensely appreciated.

Hello, how exactly did you update to version 2.1.3? Did you just transfer the new BetterNpc.cs file or follow the instructions in the archive?
Can you send all messages from the console after o.reload NpcSpawn and o.reload BetterNpc? And just in case, please send the folders oxide/data/BetterNpc and oxide/data/NpcSpawn, and the configuration files NpcSpawn.json and BetterNpc.json
