Playing on 2b2t which uses version 1.12.2. I have been using multi-connect on the server for a few days using Minecraft launcher 1.16.5 and 1.16.5 fabric mods without issue and connecting to 1.12.2 server using multi connect.

While everything was stable for days the client started crashing the moment i activated redstone pistons.

Here is my crash log: https://paste.ee/p/TWQRI

Thanks for any help

You are right the issue wasnt related to multi-connect. Also i do not wish to update im on this version for a reason.

Either way i removed some optimization fabric mod i forgot i had which solved my issues. Thanks for checking. Love your project!

Take a vacation a lil pent up sounding still love u <3

1.16.5 is not supported, update to 1.17.1. This issue is not related to multiconnect anyway
