BSP Brush crash bug

Hi Guys,

here I want to report a bug with the bsp brush system. The Editor crash when you do this:

For example: create a box, split some edges and then merge two vertices. Next you activate ‘Tessellated’ in the Brush Settings. When you now try to undo the Tesselation the Editor crash.

Hi ,

Unfortunately thus far I have been unable to reproduce this. Do you have your crashlogs so I can take a look. Further, would you mind posting your dxdiag here? Thank you!
