Entity creation not working on 1.20.2 with magic version 1.8.12

https://cdn.discordapp.com/attachments/511088611769188353/1211897474055405588/latest.log The log is about 10mb too big for github to upload

The error I can see with my layman eyes is the following being repeated

Repeated with this plugin list

[LadyHaley]

still happens with only these plugins on 1.20.2 paper build #318 Same config worked fine on 1.20.4 with same plugin versions downgrading my magic version one version has resolved the issue on 1.20.2

[NathanWolf]

Can you please try this dev build here?

https://jenkins.elmakers.com/job/MagicPlugin/4271/artifact/Magic/target/Magic-10.9-SNAPSHOT.jar

This looks like an incompatibility issue with something the Spigot team did in the middle of 1.20.x, I think the dev builds have a good fix for it in place. Please let me know either way :)

[LadyHaley]

The issue still persists with this version

[NathanWolf]

Oops, I see now I only applied the fix for 1.20.4, please try this one when you can:

https://jenkins.elmakers.com/job/MagicPlugin/4274/artifact/Magic/target/Magic-10.9-SNAPSHOT.jar

That should have the same fix, but for 1.20.2

[LadyHaley]

The issue still persists with this version also the snapshot builds are replacing RP icons with Skull icons

[NathanWolf]

Hm, strange- maybe this something different. Can you please pastebin the error again with the current dev build? The line numbers should be different, at least, it may help me narrow this down.

The spell icons have all changed to skulls, the RP has been changed to match. You can undo this if you need to (like if you're using a custom RP and don't want to update it). See the changelog for more info on that:

[NathanWolf]

Ok, thank you for your patience- this problem is really ugly, I've never seen differences between Paper and Spigot like this, or differences between minor versions, they really made a mess with this change :(

That said, I'm hoping this build has a real fix now:

https://jenkins.elmakers.com/job/MagicPlugin/4275/artifact/Magic/target/Magic-10.9-SNAPSHOT.jar

[LadyHaley]

That looks to have done the trick, thank you!!!
