ModernRegSyncFix
ModernRegSyncFix is a Fabric fork of RegSyncFix that lets a player join a server despite registry sync errors.
What it does
The mod bypasses errors that occur during registry syncs between a server and its players. When a registry mismatch would normally block a connection, it lets the client proceed despite the mismatch. Server owners can also turn syncs off entirely, so clients connect without a sync check.
Key features
Registry sync bypass
Lets a client continue past registry sync errors that would otherwise stop it from joining.
Sync disabling on servers
Server owners can disable registry syncs entirely, so clients connect without performing one.
