It happens in all the scenarios, as far as I can tell (even MBT). A good test scenario is #726 (Battle for Rome). If you buy some heavy artillery and target hexes 22,62 or 29,61 or 50,52 or all of them you should see the multi-hex building(s) disappear if they get a direct hit in the top left corner. It doesn't happen every time there's a direct hit though.

I've attached before and after screenshots that shows the building at hex 29,61 is fine after being hit but 22,62 vanished.

I have my animation level set at 1 and sound turned off. I haven't tried your suggestion yet regarding that but I will if necessary.

EDIT: I can't figure out to attach the screenshots. They're in the 'attach files' section under 'additional options' but they don't appear when I post the message.
