I t seems to be that there are still errors in the Gerber Generator and that we cannot fully trust that what we on the design screen, will be transferred to the Gerber. I have a PCB with a chip using the MSOP-8 package and on this chip some legs has to be connected. In the two images below, you can see on the left hand side pins 2 and 3 shows the track between them on the Gerber viewer (although it seems to have a split in the middle that should not be there, and between pins 5 and 6 which is done in exactly the same way in the designer, there is no track.
