This is a year old nearly - closing.

It crashes with this everytime I start the server. I tried resetting the world but still nothing.

try removing mo creatures and custom spawner and see if it persists.

When I remove Custom Spawner and Mo'Creatures it works. I would like to use these mods tho if I can.

I also found this issue with Pam's Havestcraft.

It makes it so when you fly around for a bit, and load a new chunk it will try to generate the Fruit Tree but it can't because its the BetweenLands world so then the server crashes.

Could you make this mod Compatible with Sponge?

I have been doing some testing, and it doesn't look like the mods are causing it because on my server I'm using "Sponge" or in other terms "SpongeForge" I ran the server with Mo'creatures the CreatureSpawner mod that is needed for Mo'Creatures and HarvestCraft, and it worked just fine with no issues. I then put in "SpongeForge" and that when I started getting the loading error in the console and then the game would crash.

Please keep the issue focused on one problem. For other problems, make separate issues.
