I actually noticed this several months ago, but now that much more people have access to 2.25 I thought I would post it. If you do a CSG op on a mesh and then try and beutey fill the resultant mesh (please don't ask why I tried this in the first place)... a dialog will pop up that says
'wanna crash?'
The only option you are given is
'Yes please!'
you keep clicking on it and it keeps popping up for while. never had it crash me though
I don't know if this is a general beauty fill thing or not, only noticed it on booleaned meshes (dunno why that would be though...)
