I got this while trying to create and open worlds

[18:57:37] [Server thread/INFO] [STDERR]: [java.lang.Throwable$WrappedPrintStream:println:748]: java.lang.IllegalAccessError: The Botania API internal method handler has been overriden. This will cause crashes and compatibility issues, and that's why it's marked as "Do not Override". Whoever had the brilliant idea of overriding it needs to go back to elementary school and learn to read. (Expected classname: vazkii.botania.common.core.handler.InternalMethodHandler, Actual classname: speiger.src.botania.InternalHandler)

ok I solved it it was a new botania plugin attempting to allow the non-flower decay

Lmao
