Issue is related to Minecraft modpacks:
I add More Overlays Updated mod (https://www.curseforge.com/minecraft/mc-mods/more-overlays-updated) in my modpack.

I delete Soggy's Guns, and More Overlays is deleted automatically afterwards. I'm sure - there are no dependencies between these mods... If I add More Overlays manually, everything works fine!
I created a "Test" profile, and installed only one mod - More Overlays Updated. Here's the result:
