      Description

      Expectation: no errors
      Reality: Subject errors upon connecting to server.

      To duplicate:
      1. Have two instance of the SAME server.properties world (with same seed - server.properties attached) running on the same server (in different directories) but with the current dev build on port 25000 and version 1.8.8 on production port.

      2. Logged into dev world with dev client.

      3. Screenshot shows errors:
