The periodical BSpline have corrupted second vertex with the next details:

The tolerance is huge. If decrease - everything is working perfect.
I'm not sure what to do on that case

[dpasukhi]

There 2 possible ways: extend shape fix to handle not only increasing of Vertex tolerance, but decreasing either.
And second - validate and fix vertex inconsistency during sweep.
I will probably will do both. But originally issue related to the strange file, but indeed no ways to fix it back...
