I'm hoping someone could help me in figuring out why my server isn't working with the new update.

Thanks for the assistance

Version 5 adds Twilight Forest which tries and add a world with ID 7. To fix this go into TwillightForest.cfg, edit I:dimensionID to a free dimension ID. This should fix it for you

Okay thanks, that was the reason. I guess even setting the DIM to a dimension that I had deleted doesn't work; it has to be a fresh dimension never used before

For everyone who did this (me included), everyone who wants to travel to Twilight Forest must change the dimension ID in their local configs to match the server dimension number.
