COSTAR

This simple mod fixes a compatibility issue in Minecraft versions 1.9 through 1.12 that affects Fabric users. The problem is related to the root.tick.level.entities.blockEntities directive in the profiler: it uses the Class#getSimpleName method to determine location names, causing Fabric to display different names compared to vanilla.

The issue arises because Fabric renames almost all symbols in the game file for compatibility with an intermediary layer. COSTAR mod resolves this problem by replacing the mangled names with their original equivalents.

In the gallery below, you can see a before-and-after comparison using the mod — the difference becomes obvious.
