Hi Nathan we are getting quite hefty console errors when tinkering around with magic we arent sure why. Hoping you could help, many thanks.

That looks like it would be from a bad (possibly outdated) saved item. Do you have anything saved in the plugins/Magic/items folder?

Unfortunately the way config loading works and how that error is generated make it very hard to tell what item is to blame.

Many thanks for the response Nathan. So we've done a bunch of indepth testing. We removed the items which we had many this didnt fix it. We then made a test server with just Essentials, Vault and Magic and it still spouted this error

We've been working on this server for more then a year and are using 1.20.6, we cant update to 1.21/more recent version.

Ok, thanks for all that testing!

It's possible, then, that I put some kind of 1.21-specific item in the builtin configs. I'll see if I can narrow that down.

Sorry about that!
