This appears to be a serious bug somewhere, but I as of yet can not tell where it is originating. I've verified separately, using GDAL utilities, that the COMID field is indeed non-zero. I will post an update on progress later, but this may take much time to track down.<span class="HOEnZb"><font color="#888888"><br>
