Hokai,
Gmap refresh has been running ~18 hours now... will probably be done about 2200 CDT, give or take (250,000+ tiles to render, and I just generated another mess of terrain around the Hornet build site)
This was a complete refresh, I used an HD texture pack on it, if it is decent it should be the last super-long update as its cached and usually takes 1-2 hours to update thereafter.
If the pack sucks, I will probably just go back to the stock pack, and it'll be another 24+ hour regen cycle.
