Ok I recently got to play again and it works!

Wow I am amazed this hasn’t been caught until now. I’ll work on a fix

This should be fixed in 1.2.10

Not exactly related to 1.15.2 , but I tried the latest on 20w21a snapshot and had a similar error where it crashed the server , but not single player. I went into commits and pulled the 1.3 jar file from 13aa1d7 and every thing worked fine on server and client.
