[GRASS-user] v.neighors error:region do not overlap

Hi,

I need to run v.neighbors on multiple datasets for the identic region 
(extend and resolution).  One dataset has observations outside of this 
region, and causes an error: "ERROR: Input vector and computational 
region do not overlap." However, viewing the extend in v.info and r.info 
(see below) and overlaying the layers in the GUI, I see overlaps for 90% 
of my points. Is this expected behavior or do I miss something? (GRASS70 
from Repos, OS:Ubuntu 15.04)

#Code
/r.in.gdal in="./00_REFERENCE/reference_map.tif" out=region_ref --o//
//g.region rast=region_ref//
//
//v.neighbors in=pt out=pt_dens300 size=600 meth=count --overwrite //
/
