I am afraid I mis-spoke (mis-wrote?). This problem occurs because of the way that Carbonite's maps are built and there doesn't seem to be anything that can be done about it (or at least nothing has been found since Carbonite started). So, no, using the original Gathermate addon would not help. If you want to keep using Carbonite, you've just got to put up with it and continue on. Considering everything else that Carbonite does (and offer's), this is a small price to pay for using Carbonite.
Besides which, any other map addon isn't going to have the ability to have Carbonite-like maps.
