Merging tanks - beware of this

[Weasel]

Playing a game and my M10 was hunting down a De-fanged Tiger. I gave it a target armour arc and hunt command and moved him towards the LOS tiger. Even though my M10 moved within in the arc I gave it did not engage but instead kept driving straight towards the Tiger. Now normally when two vehicles meet the moving one stops, backs up and goes around, but this time the Tiger and M10 moved into the same space. The Tiger then opened up with his co-ax MG and started killing the buttoned crew of the M10, my M10 wouldn't fire because the Tiger was inside the barrel. The end story, the Tiger is as it was and my M10 is down two crew members.

Very strange and I am sure this bug has to do with the hunt command/arc combination (the arc was 360 degrees).
