[DarkChromaMC]

Hello,

I updated to the latest geysermodelengine jar from yesterday and got this error in console during startup:

It appears I need the latest packet events jar. However, I did update to the latest dev version which is supposed to support 1.21.9.

Could you please point out where I'm going wrong?

I'm using packetevents-spigot-2.10.0-SNAPSHOT.jar

Sorted, it's due to us shading PE, have updated it to 2.10.0 snapshot (wish I could unshade it but requires it due to using WorldInIt event)

Thank you @xSquishyLiam for the fast fix ❤️
