Actual Behavior

Player kicked from server with fatal error, console shows stacktrace.

Link to Crashlog or Forgelog [If Applicable]

Read the second group- there was a middle group as well, but none of these stack traces were showing in logs so I had to pull them from console. https://gist.github.com/ProsperCraft/a57724d3b47b2671c271422a4085249c

Steps to reproduce [If Applicable]

Unable, non-opped player was mining at the time.

Looks like it is something to do with packets, gonna look into it.

Never found anything. Hard to replicate. Is not legacy and wont fix.
