It is best to download the Brewlan UI mods (small / large / classic). They work as intended, assuming that you enabled them.
Advanced strategic icons mod
If you use medium set on higher res i can send you what I'm working on which is a overhaul of asi, but I've not yet finished to upload as a mod yet. Otherwise for small use brewlan as suggested.
@jip I don't know why, but Brewian UI mod doesn't work
I'm okay with any strategic icons except default one
Are you playing via featured mods? Those do not support the custom icon approach (yet).
A work of art is never finished, merely abandoned
@jip I added the mods through FAF client, but it doesn't work
Do you know how I should do it to make it work?
@rubbern Maybe close and open FAF? or make sure another UI mod isn't applied to your icons
