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.

Mappings Overview

Mappings are downloaded and parsed asynchronously. They are downloaded only once per version. Yarn and Quilt refresh their version every 48 hours to check for updates.

Mappings | Compatible Minecraft Versions | Download Size (zipped¹)² | Cached Size (gzipped)² |

|-||-|-| | Yarn | 18w49a (1.14 snapshot) or higher | 1.4 MiB | 1.4 MiB | | Quilt | 1.18.2 or higher | 1.4 MiB (+1.1 MiB below 1.19.2) | 1.4 MiB (+1.1 MiB below 1.19.2) | | Mojang | 1.14.4 and 19w36a (1.15 snapshot) or higher | 9.0 MiB (uncompressed) + 559.1 KiB | 1.3 MiB + 558.6 KiB |
