I just tried to submit a game a few minutes ago and I got an error message saying that I was using an unsupported map or scenario, despite the fact that I was on a completely random map without a change of rules. I am working on a campaign of scenarios, but this was not using anything from it. I can provide a save if it's needed.

Fleetlord. This is a problem that I have both posted somewhere in this thread or one of the earlier ones and in private email to CariElf. The problem is once you use a non-Stardock generated custom map or scenario the system keeps that information until it is reset either by loading a Stardock generated custom map or specifically going to custom map, selecting "none" and then going back to the standard random map you normally use.
There is a fix, but you may or may not want to do it yourself. You can edit the SaveEndGame with a hex editor and about the bottom of the first page shown in most hex editors you will see a MAP information. Starting at the Custom Map ascii, change it to "None" and then swich over to the hex data and enter "0" until all the text for the type of custome map is eliminated. This will allow you to submit the game without changing anything else about the game.
Or, if the discusion of the last few days (or has that been weeks?

) make you fearful of doing that, ask CariElf to do it for you. She may or may not.
