Change Mod ID when importing for .mcr file

Also, a weird glitch where all of the ids are messed up, and the game says that they don't exist, while they still appear in the inventory as missing textures.

Apparently, the mod id had some problem, and now everything is registered under minecraft:[id] instead of modname:[id]

Most likely it was too short, but now I can't change it, since when I clear the workspace, and then import the file, it overwrites the original data. I think you should be able to change it while using an mcr file
