different civ's units in the same tile

[uat2d]

i found this bug in Warlords, so its probable to it be also in Regular Edition, and I don't know if someone posted it before, but:

if I move an unit to a neutral tile, and in that tile there are units from different civs (a warrior from Ramesses II and a scout from Mehmed II) , it only asks me if I want to declare war to one civ (Mehmed II), but not the other civ (Ramesses II)
If I declare war (to Mehmed II) my warrior kills his scout and I automatically enter that tile, sharing it with the other civ (Ramesses II), and if I don't declare war, I enter the tile and it doesn't asks me if I want to declare war on the other civ (Ramesses II)
the save below allows you to see for yourself the bug

So ignore it. If you want to declare war on Ramsses II, Alt+click on his name.
