Posts from The problem of the unpainted surface.

While creating a scenario, I encountered a problem: when editing regions for scripts, the map froze and crashed. After opening it, all the tiles became blue (empty, uncolored), meaning all roads, terrain, etc., were reset. I tried to repaint them – it paints, saves, and says everything is OK, but when I open it again, the same blue mess appears. I deleted the regions – it didn't help. Basically, the map is broken, and I don't know how to fix it. I don't want to create it from scratch. Has anyone else encountered this? Please advise on what you did.

This is a very common problem. In the original game, it was easily solved: simply repaint, and everything would return to normal. If it resets, then it's likely that there's nothing more you can do. It's best to ask around; you might find an answer.

This is related to a crash involving Ground.bin. A possible fix is to close the map after the first error of this type, open it with an archiver (WinRAR, 7-Zip), and also open the folder GameFolder/Editor/H5MMods/MapName/Maps/Multiplayer or SingleMissions/MapName/ and copy the Ground.bin and Underground.bin files (if they exist) from there into the map archive. After that, save the changes to the map archive, close it, and rename it. Make a copy (!) and check it in the editor. In most cases, this should solve the problem. P.S. I don't think this is a current issue, but just in case someone needs it.

}{0TT@6bI4, generally speaking, this is sometimes a relevant issue; it happened to me periodically a couple of years ago when working with maps. I strongly recommend that everyone make backup copies of Ground.bin and Underground.bin (if there is one, of course) from time to time if they spend a lot of time working on maps.

It's not necessary to create backups of Ground.bin and Underground.bin if you're making copies of the entire map!
