So I'm in the chapter Only Human, in the part where I had to clear some mines for some friendlies who are driving an APC and I get the gunner's seat. After I destroy the attacking Ceph gunship and clear some more mines ahead of the APC, it always gets stuck and flips over. This happens always in the same spot, no matter what I do. Also after the APC has flipped over, it can be sunken to the ground by shooting it. Has anyone else encountered this? :/

Here's a video to show you what I'm talking about. You can see the bug in 1m33s and again in 3m00.
