Description (last modified by )
A shapefile polygon set A has been cut using a grid polygon B using a v.overlay AND operation. The result is expected to contain all the A polygons that are enclosed within the grid polygon B.
The output is almost as expected but several A polygons within the B rectangle are missing. GRASS version is 7.0.0.RC1. Here is the io console log:

Hi,
I've checked the same workflow on the stable 7.0.0 release and it seems to be OK. You may close the issue.
Best regards, Deyan.
