Hello, it's not working on Paper 1.20.4 build 497 with the following error:

[06:16:19 ERROR]: Could not pass event PlayerExpChangeEvent to XPBooster v1.3.1
java.lang.NullPointerException: Cannot invoke "java.lang.Double.doubleValue()" because the return value of "java.util.HashMap.get(Object)" is null

Could you explain how this occurs? I cannot seem to reproduce this error, thank you!

Huh? Sorry but i can't either, just played with plugins on a testing server and maybe did something wrong 🤔 I will reopen with reproduction steps if it happens again then…
