To apply this new update well, it is necessary to delete the files mentioned above, so that the new ones are loaded.
Finally, the structure of the database has been modified, so it is also necessary to delete the file: NPCAlive.db. You can find it in the Data folder.
If you don't want to lose the information already contained in the database, you can contact me via discord, to be able to help you.
This new update prevents the npc from losing their skins when restarting the server, so it is very important to reload a new database. If this is your first time using the plugin, just install it and go.
