This mod allows for upgrade items to have a chance to not be consumed and used again.
Completely configurable in the config, you can set the chance for an upgrade to not be consumed, and the maximum upgrades an item can give before the consume is guaranteed.
Reworked to be fully server-side, so only the host needs the mod.
Compatible with Shop Items Spawn in Level and probably any other upgrades mods that use the base upgrading logic.
