[Bug] Invisible transports after loading

[Bianary]

After loading a save, any transports in the water are invisible.

Any new ones during play display fine, and the units work fine, you just can't see them.

(Tried to add a screenshot but it's 300 KB which can't be attached easily. Anyway, the transport model is just not drawing on the map but things like the unit power indicator, circle around it when selected, pathing from it, etc. are all there. The model is drawing in the lower left selection display when the unit is selected.)
