I believe I have located why this happens.
The Real World Mod places files in the C:\Users\Username\Documents\Wolverine Studios\DDSCF 2018\Leagues\NCAA\HTML\Images\Logos folder.
Inside here I can see that files have been created for the Endzones. 1_ez.png, 2_ez.png etc... these are stretched images of the actual team logo, 1.png.
I am going to try and script something that can fix this.
