As mentioned in the other thread, this is a system bug that was corrected in the 2.4.2 patch.Tabadi said:#35 - Unsupported units
If you have a HUGE civ (~120 cities +), new cities will produce NONE support units. Move supported units into these cities, click the unit then "Support From This City" - the unit will then become "NONE" and its home city will no longer need to provide support.
