There were a couple of problems that could have caused this in the 1.2.0 version which we hope we have fixed in the 1.2.1 release.

The control tree and source both reflect the contents of the AST model that is maintained internally. If that gets corrupted (usually some source position offset isn't updated propery), it degrades quickly from that point on.
Test cases (especially using the 1.2.1 version) would be very helpful. We would be looking for an initial sample class (could be something made up just for the test case) and an
exact set of steps (e.g., move this, change this, switch to source view, switch back to design view, etc.).
