Could we get a backport for 1.19,.4 that is kept up to date with the latest release? Just until Spigot gets their stuff together and fixes/re-adds the custom enchant stuff, as Spigot decided to remove that in 1.20+ which causes a lot of issues in slimefun addons, which means that unless someone finds a fix in the slimefun community, that a bunch of addons break on 1.20 or don't have all their items from 1.19.4.

As much as I would love to back port I've decided to just close these as I don't have the time and when I do, I frankly would rather work on new features and fixes, than back porting the mod. If anyone does unofficially then great but otherwise I do not plan on back porting. Sorry!

Iirc the breaking change was in 1.20.4 and isn’t broken in 1.20.2, I can look into a backport similarly to #20 but it won’t be a top priority, and it would definitely have to wait till im done with my WIP custom model data feature, since it isn’t done yet

If it helps I tried to force load the latest mod version on 1.19.4 and only had a problem when joining a server with this error:
