Jade Sable Compat

# Jade Sable Compat  Jade Sable Compat is a NeoForge client compatibility mod for Minecraft 1.21.1. Its job is simple: when a block belongs to a Sable sublevel or moving construction, Jade should identify the block you are actually looking at instead of some wrong block from the main level. ## What It Fixes - Corrects Jade block selection on Sable sublevels. - Makes Jade tooltip title, icon, and selected block line up with the actual block under the crosshair. - Uses a Sable-aware client retrace path so moving constructions and sublevel rendering use the right pose during tooltip targeting.
