I don't know if this is a problem for anyone else but I keep finding that my imperialcity map keeps jumping back backups when I go back to work on it. The most recent got rid of the back wall and I find it incredibly annoying to keep having to rebuild things, is there any way to fix this problem?

Did you unload it after working on it or did you leave it loaded? If you left it loaded try unloading it every time you log off. If this does not solve the problem Im noticing some other things and I might need to clean out some of the old maps and backups to make the files smaller I think that could solve some issues.
