What does this mod do?
All errors displayed in the console and all crash reports will be remapped from unreadable production names (e.g.
net.minecraft.class_310) to readable mapped names (e.g. net.minecraft.client.MinecraftClient).
This allows mod developers to more easily identify issues in a non-development environment, as the errors are instantly human-readable.
