GlassSync
A mod for Hypixel Skyblock that fixes the clientside desync of glass pane block states on 1.21. This allows for easier aiming at glass panes for gemstone mining.
About this Mod
This mod fixes Hypixel Skyblock's Glass Pane client blockstate desync issue on 1.21.5, allowing for gemstone mining to be easier and more efficient.
This mod makes the client update the blockstate manually, rather than waiting for an update packet from the server. The block shown on the client will then replicate what is on the server.

Does GlassSync need to be installed on the Minecraft server?
No. Modrinth marks GlassSync as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.
Which version and loader does GlassSync require?
Use a file for fabric and your exact Minecraft version. Supported versions include 1.21.11, 1.21.10, 1.21.9. Files for different loaders are not interchangeable.
GlassSync is not working – what should I check?
First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
