After reviewing your changes in 0.0.4, I came to notice that the terms of the MIT License were not met yet.
"Originally created by Laserzwei, who is too much of a jackass to be thankful for help. All files in this zip, save thumbnail.png, BigWheelMinerSheet2.png, and HR-BigWheelMinerSheet2.png are under MIT license owned by Laserzwei. You must include the previous sentence and this one to avoid his wrath (and legit legal problems). thumbnail.png, BigWheelMinerSheet2.png, and HR-BigWheelMinerSheet2.png are not under any copyright and may be reused freely."
Still doesn't fulfill the criteria: It is required that you add an appropriete license file containing:
Copyright 2019 by Laserzwei

*License end
You may specify which files are affected by the license or those which are not, by writing them above or below the minimum required license text stated above. The licensefile is to be put in the highest hirarching folder which still contains files belonging to the copyrighted software (as of 0.0.4 that is the mods' rootfolder).
P.S.: I think you didn't want to actually write this:
"(...)All files in this zip, save thumbnail.png, BigWheelMinerSheet2.png, and HR-BigWheelMinerSheet2.png are under MIT license owned by Laserzwei. You (...)"
So you might want to change that as well...
