Just in case anybody runs into the same problem with the zone fills, I did have some success with a workaround. In the freerouter, you need to manually place a route from a GND pad to the fill zone. So in this case, I placed a route from the mounting hole to the zone around the edge of the board. Even though the fill zone is already touching these pads, and the router certainly thinks the zone is grounded (since it routes all kinds of things to it) I suppose it really never considers the zone to be connected to the GND net unless you manually route it. Make sure to do it on both sides if you have a zone on both sides. Also, the manual route seems to be pretty finicky as even after manual routing, it sometimes still thinks they are not connected. You can, however, stop the router when it goes berzerk (left click) and place another manual route, and restart the autorouter. I haven't tried placing these manual routes in kicad before the export, but that may work as well. Now I get 99% of the way through the autorouter and it hangs on a routing a couple of pads that are close to each other and have a clear path. Not sure why it does this but that is easily manually routed and the optimizer will then run after that. Again, thanks for the help.
