Hello, I'm sorry for the long answer, did you just install NpcSpawn.cs 3.2.2 (first version with this update) and write to the console ConvertLootManager 1 time? Did you manage to solve the problem? Do you have backup files before starting the update?

No, I didn't see that there was an update before 3.2.4. I haven't done anything since getting the error. I don't have backup files from 2 days ago, no.

Please, if exitst, send config files:
config/NpcSpawn
config/NpcSpawn_old
config/BetterNpc
config/BetterNpc_old

and data files:
data/BetterNpc
data/BetterNpc_old
data/NpcSpawn/Preset
data/LootManager/LootTables

There was no NPCSpawn_old. I am not using BetterNPC and the NPCSpawn/Preset folder was empty.

lootmanager loottables.zip NpcSpawn.json

I think this is my mistake, because almost all tickets with any problems were related to BetterNpc, I apologize. Let's take it in order.

Your error was due to the fact that you had 2 files with the same name but with a different extension in the data/LootManager/LootTables/ folder. But you didn't need the conversion itself, because NpcSpawn presets are currently used only by BetterNpc, meaning you have nothing to convert.

For now, just make sure that you don't have UpdaterNpcSpawn.cs in the plugins folder, delete the configuration NpcSpawn.json and upload the latest version of NpcSpawn.cs to the plugins folder.
