Exception in server tick loop

[CrimsonSemtex]

After adding all my mods and everything loading up fine, I go to create a singleplayer world and it load to 100 then crashes saying:

The game crashed: exception in server tick loop Error: java.lang.NoClassDefFoundError: net/luckperms/api/LuckPermsProvider

Cobblemon GTS requires LuckPerms to work

If you already have Luckperms, try different builds of both mods until you find a working combination

Yes this error is with both of the mods. What do you mean by different builds? thanks for the reply!

Try the 1.4.0 build:

Does it work without Cobblemon GTS?
