1.16.4 Failed to synchronize registry data with server LAN

[Teedledee]

Trying to play on a modded LAN server with my friend, when I try to join their LAN world I get the "Failed to synchronize registry data with server, closing connection" message, and they get the same message when trying to join my LAN world. We have the same forge version 35.1.12, all the same mods with the same versions of those mods as well as the same configs.

Not sure if this helps, but I copied all of the mods from my folder into a zipped folder which was then sent to my friend for them to unzip and drop all of the mods into their mod folder, the same goes for the configs.

Fixed the issue, one config didnt match, downloaded randompatches to solve badly compressed packet afterwards.
