[hypherionmc]

That error usually means that Simple RPC failed to load, most likely caused by a config error.

There should be an error log earlier on for that. If you don't see anything, send over a copy of the simple rpc config and I'll take a look.

Alternatively, send over your latest.log file

[ModernGamingWorld]

I have a simple-rpc.bak and a .toml file. The error appeared randomly and went away after I disabled this mod and the Simple RPC mod

[hypherionmc]

The .toml file will be the one loaded. .bak is one created when the mod updates the config for structure changes

Alright your config seems fine.

Could you send a copy of your latest.log with the mod enabled please?

[ModernGamingWorld]

will once I figure out why even now with your mods disabled. My pack won't load up now

[ModernGamingWorld]

latest.log

[hypherionmc]

Sorry for the delay. Just got home from work.

Okay so the CraterLib error is caused by Simple RPC not loading for some reason.

But, overall it seems like forge is giving up loading right after nochatreports loads.

So something is breaking, which is possibly why simple rpc is not loading either
