During the entire beta phase of Miscreated self hosted servers are NOT officially supported and will mostly likely be changed during each update.
Due to the fact that self hosted server admins can adjust item spawns the Items tab on Amalgamated kiosks is disabled on self hosted servers - the Skins tab remains fully functional.
It's recommended server admins join our community Discord server for help: http://discord.gg/miscreated - Help requests go in the #server-admin-help channel.
NOTE: This document describes the manual steps needed for setting up a Miscreated server. It is highly suggested most users instead use Spafbi's Simplified Miscreated Server Setup script to handle setup, updating, and running of the server.
