Hi,
i think a alias using "Enabled_Worlds" will break if that wanted world is not loaded, In my case during server start. SimpleAlias enables before the server is loading that world.

Server version: Paper 1.18.2

[SimpleAlias] Failed to load alias 'test.yml'. Cause: The section 'test1' in parent section 'Actions' is invalid ('Enabled_Worlds' contains an invalid world name)
