Chunk loading exception

[TaxMachine]

Whenever a chunk is loaded (ChunkLoadEvent) I get this stacktrace

java.lang.IllegalArgumentException: x out of range (expected 0-15, got 720) <- this number is never the same

I use purpur as the server software, its a paper fork for optimization

[xGinko]

I can see a main class existing. Are you perhaps still on a 1.x release?

[TaxMachine]

plugin version is 4.2

[xGinko]

Yeah that version never existed on this fork.
