Countless bugs and crash with the new R23, never experience something like this with C4D.
It's really frustrating and slow badly my workflow.
Wished I never install this update.
Many issues for me too with cut tools, they not working with 'Restrict to selection' neither the 'Regular Slice'. I can use the Loop cut to sort it out but it will mess with my UV. Can't wait for SP1 since it really slow my workflow.
