More major progress tonight. I deleted all of the planet square data and now have the planet editor displaying the planets tiles under the new system. Below is a screenshot of an ice planet under construction. Now I just need to make sure the rest of the places in the game that display planet surfaces get changed over and one of the major legs of this rewrite will be complete.
I still have a TON of database work to do to get all of the planet tile graphics into the system, but there is a slight hint of a light at the end of the tunnel.
