The Issue
When loading a server with custom portals (and dependencies) it crashes.
I believe the specific problem is from this line Cannot load class me.lortseam.completeconfig.gui.ConfigScreenBuilder in environment type SERVER

Server Log
latest.log

Knew there was something I'd forgotten to test. Should be fixed in the new version.
