The situation is as follows:
In location GRS mapset PERMANET I have MASK (with projection of 2180 based on GRS elipsoid)
in second mapset let say jarekjaI have map which is to be reprojected to other location (WGS). In that mapset no MASK is present.
In location WGS mapset PERMANENT I reporject map from location GRS and I have only fragment allowed by MASK from GRS PERMANENT It is intended or some bug?
