My sister and me were playing for some days in a world via LAN. We are using about 30 mods, and since today when she wants to connect she gets the message "Failed to synchronize registry data, closing connection".
I have no Idea why this happens, I updated all mods and forge and made sure we are using the same versions.
For some reason, when i create a new world and open it to LAN she can join, but I dont really feel like doing everything again. Has anyone an Idea why this could occur and how to fix it?
As I said we were playing together, then she disconnected and tried to connect again about an hour later, but the Error occured. We both didtn change anything at our installation.
