If you are experiencing any of the following issues with map generation:
- Start locations very near to opponents
- Start locations on impassable terrain (mountains or sea)
- Start locations completely blocked off from other players
- Maps with rivers running across the sea
- Other strange terrain, especially if it would affect gameplay
Please open your debug.err file after this happens and look for a line like this:
Debug Message: Map Random Seed: 1253569728
Then paste the number there into this thread with a description of the sort of map issue you had. Please do not respond here for issues resulting from starting a second game in the same session or loading a save, as those are different problems.
If the map issue you're seeing is one of the "other" kind, please include a screenshot too so we can see what sort of issue it is.
Update: We should have enough examples of bad rivers now, please keep further reports to start location issues.
