I don't understand what you're referring to, can you tell me what you mean? What entity tooltips? My mod shouldn't adjust anything outside of its own scope - it shouldn't change how other things operate. What item icons in entity tooltips do you mean?
This is what my code does:
It adds a button to open a menu
It defines some sprites specifically for that button/menu
It handles the menu interface and item spawning
It includes some checks for the quality dlc.
Can you disable my mod completely and see if the issue still exists? If possible make some screenshots of what you're seeing?
My sprite definitions are specifically named with my own prefixes and are only used within my mod's GUI elements. I don't modify any base game GUI styles or prototypes that would affect tooltips or icons in other mods.
