Hello, the Discord name you linked didn't come back as valid. So I've uploaded the images to imgur and will provide them here:

I'm specifically referring to the 3 Loadout management buttons for saving, loading, and deleting infantry loadouts.
Additionally, I've discovered that in the inventory screen, the new Large Item object panel is misplaced and is lacking the correct default "empty" icon, while also causing the other background images in the center of the screen to be missing.
Essentially, all of the new UI that was added with the Infantry update in November. The only other mod I have installed is a map-texture mod, which could potentially also be doing it, but this seemed like a more likely mod to touch these parts of the UI and I wanted to confirm that it doesn't look like this on your end before I head there.
