I noticed that every time i shut down my Server PuzzlesLib in combination with Universal Enchants and Forge Config API Port spam the log with errors.
I don't know if the error is because of other mods, but the errors seem to only mention this 3 Mods.

Errors thrown in log when Server is shutting down:

[Thread-2/INFO]: Reloading server config for universalenchants
[Thread-2/ERROR]: Calling server config when it is not yet available! This is a bug! Current loading stage: MISSING_DATA
java.lang.Exception: Server config not yet available

Resolved in v4.1.0 for 1.19 since the whole system has been overhauled.

Regarding 1.18, this is not a breaking bug, the spam essentially means nothing, it's just for me.
