Install in the game only; not needed on the server
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.
