v3.3.3-beta - side effect of pieces update?

As mentioned in another thread, working more with v3.3.3 builds, I have happened across a more concrete symptom that would explain why a module used under v3.3.3 might exhibit the same problem when subsequently used under v3.3.2. The Buildfile is getting corrupted, but not necessarily by the Game Piece Refresher. I have opened a new thread here.
