Asset Validator

Asset Validator is a mod that was used to assist Jumploader with Fabric 1.16 snapshot/pre-release modpacks.

It was intended to "fix a bug with snapshot versions of Minecraft (1.16+) that caused assets to fail to load in certain circumstances. The assets that failed to load may include language files, textures, models and more."

It has been deprecated as it was fixed for 1.16+ release versions.
