Installed Darker icons, which in battle properly loaded the darker icons for the other team, but my for my team it still loaded HAWG icons. I did a clean install both times.
Rolling back to Aslains_WoT_Modpack_Installer_v.1.9.1.0_04 to see if that resolves the icon issues. If it does resolve the icon issue, I will wait for the next version to be released. Not a huge deal, just a bit annoying trying to figure out the new icons when use to a specific set.
