Summary: unit_virtual_destroy() assertion
'!unit_transported(punit)' failed (launching missile from sub to adjacent
tile)

Discussion Lock: Any
Operating System: GNU/Linux
Planned Release: 2.4.0
_______________________________________________________
Details:
Found a reproducible assertion failure on S2_4: with a submarine carrying a
missile adjacent to to enemy units on the coast, move the missile to the units
(i.e. attack). Both attacker and defender clients hit this assertion failure.
I assume the problem is that the previously invisible missile unit becomes
visible only to be destroyed, and that the transported status at the client
ends up not what we want.
I suspect this isn't related to bug #20542.
Haven't checked if something similar happens with Marines.
