Trying to run Curse Roguelike Adventures and Dungeons 1.21, however it constantly turns off. I looked in the logs and it seems to start here:
[00:08:05] [Server thread/ERROR] [FML]: A fatal exception occurred during the server starting event
net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from Open Terrain Generator (openterraingenerator)
Caused by: java.lang.RuntimeException: OTG has detected that you are loading an OTG world that has been used without OTG installed. OTG has fixed and saved the world data, you can now restart the game and enter the world.
