Please report any Bugs or issues you have using Post Map or Doge Tile Editor! Will be happy to look into it. 

Known Issues currently:

GDI/Lag crash outs with the massive Biome painter.  If it happens to you let me know what you run. Would recommend going down a few sub-cells or chunks in the mean time. Windows form apps have pretty harsh limits for interfaces. 

Skipping with brushes on  the massive Biome painter. It is on purpose when zoomed out to prevent an obscene of lag for slower computers but will have a button to turn off that limit for higher spec people in the future.
