The Network Compression Threshold on the server is actually set to 128. I do not know what version of the mod the player has, I have told them to update to 1.4 - don't know yet if this has fixed the issue.

They were not using Raknet when they had this issue.

Seems related to #1, except with an alternative reproduction step of manually setting the compression threshold lower in server.properties.

The work around seems to be setting the compression threshold to match the amount the error shows, 512, as #1 cannot be reproduced when the threshold is set to 512.
