Doubling of tube when moved after validation

[Drmabuse]

This only happens on hollow tubes with the move tool after validation. The drag tool works fine…
It seems to be the inside part of the tube that gets left behind.
Strangely, you can move the tube ok at the thick end, but as soon as you go back from there the doubling occurs.

I just solved this. It was the connected topology option. It seems to work differently for tubes.

It needs to be turned off. I just made a custom move brush called “MoveTube” to solve the problem.
