The exception is different than https://github.com/kangarko/CoreArena/issues/492. This occurs without entering paper code. As you can see the top error comes from the plugin.

And in the other report, it was SimpleCuboidRegion.java:66, but this exception is in SimpleCuboidRegion.java:68

You're right. Can you please try this file? https://ufile.io/y3rn4966
