I use a mod for icons: "Advanced Strategic Icons mod installer 3.3.1", but lenkin's YouTuber has both this and that mod working at the same time. My mod mods: "redux acu icon" and "ACU highlight" don't work, but the "Advanced Strategic Icons mod" work normally and the SIM mods too. I tried to turning off the mod "Advanced Strategic Icons mod", it didn't help.

What should I do?

Mod UI "ACU highlight" doesn't work for me what is the reason?
