728 helix turns mangled when wiggle backbone.

[Bletchley Park]

I used a cut to separate the first helix from the chain, used rebuild to turn it into a helix, then used wiggle backbone to let it shake itself into shape. The result was a very mangled structure with residues that do not resemble a helix anymore. I have posted it as mangled_1 for the scientists.

In fact, the whole structure will go haywire when wiggling all.

We think we've found the source of this bug, and even more importantly: the solution for it!

Thanks for uploading your mangled_1 model to us!
