If you look at the bottom section of the image, you'll see the bases of the towers flying away leaving the rooftops in place. On the far back wall [at top right] you'll see that two wall sections have joined the towers and jumped into the town. This happens in the first second or two of the animation. After the 2nd second, nothing moves. [nor does anything return to its original position] There are no key frames on the time line...anywhere. Anyone have any ideas on what causes this?

Once upon a day, I had a similar problem with a jointed figure of a woman. I posed the problem on this forum and it was solved with the simple expediency of disabling 'PHYSICS'. But I tried that again, and the problem persists.

I hope there's a solution here since my previous two questions [cyclical motion, and motion paths] were going to happen in this model.
