Sponge spams that dimensions are disabled

On my server, I have a mod that adds a dimension (Flansmod adds an apocalypse dimension, DIM2). I disabled the nether in server.properties, and thus other dimensions (as intended).

However, sponge (only sponge, this does not happen when sponge is not installed) spams the console log with:

05.01 17:21:51 [Server] INFO [17:21:51] [Server thread/ERROR] [Sponge]: Could not load world [DIM2]!
05.01 17:21:51 [Server] INFO [17:21:51] [Server thread/ERROR] [Sponge]: Unable to load world [DIM2]. Multi-world is disabled via [allow-nether] in [server.properties].!

So fast that I can’t see anything else. Is there any way to disable this? I know DIM2 can’t be loaded XD

As you can see, it happens multiple time per second.

This is probably caused by a plugin/mod that really wants DIM2 to be loaded - and doesn’t give up.
Check config options for the mod to see if you can disable this behaviour.

Turns out it’s Flansmod’s ‘Apocalypse’ dimension, and there’s no way to disable it.
