Comment 16 for bug 896113

New v02 binary should fix this issue. If a cell had no free infantry subposition, the function returned 0,0,0. Later this was used as coordinates and the game returned an invalid cell, which the survivors/passengers/hijackers are placed on. Now Ares checks whether the returned cell is the invalid one.

So this problem should occur if a tank in the middle of other objects is destroyed, so not all survivors/passengers/hijackers find a free spot.
