Tested with only Blackops ACU v.14 activated (no other mods used) while using FAF.
When the Aeon ACU is upgraded with the teleporter Upgrade, upon deselecting the Aeon ACU, the ACU will lose the "build table" (what buildings the ACU is capable of building) as well as "clickies" (move here icon, attack ground icon, hold fire, teleport icon etc etc, all icons) suffice to say the User Interface for the Aeon ACU breaks completely when using the teleport upgrade.
Other faction ACU's upgraded with the teleport upgrade are not affected.
