Works both in the game and on the server — install where you need it
ModernRegSyncFix
A hard fork of RegSyncFix for modern versions.
RegSyncFix is a simple Fabric mod that bypasses errors during registry syncs in Fabric API. It can be used on the server side to disable syncs entirely for all clients, or you can install it on your client and the client will proceed despite the error.
What's different?
This fork adds support for Minecraft versions 26.1 onwards.
Why?
The original maintainer seems to be inactive, and not able to be easily contacted... and a server I manage desperately needed a replacement for this mod, to allow vanilla clients to connect without Legacy4J.
If you happen to be the original maintainer reading this, and are interested in maintaining the original project, please contact me on Discord at dexrn, and I will archive this repo. Additionally, I'll clean and PR the code from this fork's last commit if desired.

WARNING
The registry sync is there for a reason. If you are using this mod you may encounter unexpected behavior if the mods are not the same as the server. The intent of this mod is for cases where you know everything should work fine but the registry is preventing you from joining.
