I think there would be still one combination corner case even when bug #20663 (when transport moves, cargo is temporarily in old tile when it's already required in new tile) and bug #19989 (info about unit movement not yet sent to client when movement causes old tile to become fogged) are fixed ot the extend of their current proposed patches. It's still possible that cargo has not yet moved when tile gets fogged.

We may get away this by the fact that also server thinks that cargo has not yet moved - so server and client are not out-of-sync about what units exist in tile getting fogged.

I have not tested, but I think it's possible to create such an situation:
1) Client A is allied to player B (sees inside transports)
2) A has shared vision from player C
3) B & C are at war
4) Ruleset has transport capable of occupying cities
5) A sees some B's transport only thanks to shared vision from C (that's a bit odd situation itself - C itself does not see inside B's transport, but still gives that information to A?). More precisely: B's transport is seen by C's empty city next to said city
6) B's transport moves to occupy C's city. C and A lose vision of the area.
