Steps to Reproduce

Moving vertices of a simple mesh, like a plane or a box works sometimes, sometimes crashes UEFN.

Expected Result

Triangle editing should be stable by large.

Observed Result

Frequent crashes with no obvious pattern. Editing a mesh might work for a while, then suddenly crashes the editor. Yesterday I had about 20 or so crashes during the day. Saving a project while in Modeling Mode also can cause crashes.
I got into the habit of not saving out of Modeling mode for that reason.

Platform(s)

Windows 10
