Comment 2 for bug 842960

The question is, what would be the best solution?
The problem simply is, that there must be the old building at the beginning, when there's actually only 0% build of the enhancement - so currently I believe the best would be to remove the old building animation after the first build segment was finished - this would keep the current animations of upgradeable buildings (with just one frame) as they are and should still be enough for better (multi frame) build animations.

What do you think?
