[Bug] Very odd loading issue

[vizthex123]

What happened?

I added some custom composting values with KubeJS, and had my game fail to load due to an error with REI. Tried it with CraftTweaker and that didn't fix it. Removed both and that still didn't fix it.

Afterward, I deleted the mod's config folder and that fixed it.

I've heavily customized REI in this pack (added a couple dozen collapsible entries, hidden a hundred or so items, etc.), but I used a JSON5 validator to check on the rare occasion I edited the file itself. Haven't had anything like this happen before trying to add my composter recipes.

Here's the full log from after I removed the compost scripts:
latest.log

What mod loaders are you seeing the problem on?

Forge

Anything else?

Reinstalling the mod after deleting the config still didn't allow it to load.

I don't know for sure, but I think Masterful Machinery might be causing it? The mod doesn't have REI support (although I did request it ticticboooomer/MasterfulMachinery#69), but I still get the error message if I disable the mod.

Edit: I updated Forge (from 47.2.6 to 47.3.0) and that didn't fix it.

By submitting this issue, I have included the necessary logs by pasting the contents into the correct location or attaching the file as an upload.

• Yes, and I did not use any paste services other than GitHub Gists.

By submitting this issue, I have confirmed my REI and REI's dependencies are up to date.

• Yes

Update: I found out that the Compost mod is what's causing it!

The error you showed along with the full log file clearly show that the error is
Failed to load plugin: dev.yurisuika.compost.integration.roughlyenoughitems.CompostClientPlugin

I'm very sure this issue is far away from being even remotely related to Masterful Machinery.

If it is somehow related to MM, REI is not currently supported in any capacity, thus any issues will not be handled as it is not an issue with MM.
