Prior Testing

If you've installed standalone:

• Does this happen in Vanilla without OptiFine?

--- This is an optifine only feature, cannot be tested outside of Optifine

Additional Information

Red Mooshroom's Custom Red Mushroom texture seems to load upon first entering the world, but randomly when refreshing the texture packs it can suddenly throw the error above and display a missing texture.
