Yeah idk, it’s a Java version mismatch. Not sure it can be fixed since Minehut defaults to Java 21.

I would get an older version and wait until minehut updates to 25
tawny falcon
I would get an older version and wait until minehut updates to 25
Yeah, I thought of that, but the other plugins I use don’t support 1.20.6, so I’m kind of stuck. I tried getting an older version of the plugin, but every version above 1.21.4 needs Java 25, and I can’t find another plugin with the feature I need that isn’t paid.

I could use 2.9.9 without issue
tawny falcon
It didn’t work for me. I still got the same error.
I tried five other beta versions as well.
tawny falcon
I could use 2.9.9 without issue
Also, it only goes up to 2.9.1.187.
tawny falcon
I swear I saw 2.9.9
Yeah, it was DecentHolograms.
pearl breach
Ohhh yeah
Too many plugins have similar names
