Expert mode isn't triggering, in the expert config in "triggering dimensions" all that it says is "{regex}.*}". How do I add nether and other modded dimensions there?

I am also using Incendium wich changes the nether alot if that helps.

Hello, thanks for the report, there was a bug in my library mod that I fixed recently, check out the latest 5.1.1 version

Alright. Thanks!
