So i've been playing as UEF a bit more lately and noticed that the billy upgrade breaks my UI, I don't know if this is a well known glitch or not but here's my replay.
If you select my ACU (from my point of view) before the upgrade you can see my health and kills. Once i install the Billy the ACU info box completely disappears no matter how many times i select my acu. If you select a unit then select the ACU it shows the units stats but ACUs picture.
Abandoning the billy allows me to see my ACU stat box again, vet and health even kills.
