Mesh object gets destroyed after move in edit mode I have a mesh object that behaves fine when I move it in object mode. But if I go to edit mode, select all faces and move them just a bit, the mesh gets destroyed - some faces disappear.
What is wrong with this object? I have more human models like this one and most of them don't present such an issue.
Left is before, right is after:
Disable the Auto-Merge option. From the manual:

When the Auto Merge option is enabled, as soon as a vertex moves closer to another one than the Threshold setting, they are automatically merged.
