I've been using the Map Editor in Tiberian Dawn to build maps. I usually work on a map for a while, save it, and then close it. However, when I come back and reopen the program and load the map I was working on later, the program will always crash. I can never finish a map because of this. The error says "The program ccwmap.exe has encountered a serious problem and needs to close. We are sorry for the inconvenience." On the bottom it says "windebug_what_happened_message." Any ideas how I can solve this problem so that I can finish a map?
Lastly, when I open an unfinished map, the terrain always reverts back to temperate. Even if I build a desert map, when I open it back up it will appear as a temperate map before it crashes.
