Found two issues with messed icons:

First off the Advent loyalist titan icon should be turned sideways by 90 degrees (counter-clockwise). Right now the titan seems to phase-jump and move sideways when zoomed out into icon-view distance. Didn't get to test the rebel titan yet.

Secondly the flagships show the right faction-based icons in the empire menu and when zoomed out, but when highlighting the ship in the empire-menu it shows the advent flagship for the tec and vice-versa (see screenshot below for example)
