I'd like to present to you something that will be of great interest to those of you who experience problems with toolset crashes and module corruption. I am making a study of why my toolset crashes occur in the hopes that I can fix the problem
Usually when I experience a toolset crash, it somehow manages to corrupt the entire module rendering it useless.. Here's an example of how it works, at least for me..

Notice the first greyed out module. Notice how the size of the file has been significantly reduced due to the toolset crashing. Not too much trouble there due to my versioning system I only lost an hour of work..
Notice the next greyed out section. I experienced a toolset crash on that version. I'm mystified as to how, my usual regime which works well for me is I close and save the area I am working on, wait for my RAM usage to go down and then cross my fingers and save under a new file name. When I reopened the toolset I opened the corrupted version, thinking everything was fine since the crash had occurred despite my usual regime, I went ahead building little bits on the mod over the next three days.
I only realised my folly when I went to export an erf and the toolset had a brain explosion. The second crash must have caused further corruption as any of the areas I havent done too much building in when I tried to open it just made the toolset crash again. These corrupted mods cause seemingly random crashes whereas the non-corrupt versions seem much more stable as long as I take care of my RAM usage.
Not picking up on this is how I managed to destroy months upon months of work for the original 12 Moonsea builds I've done..
The moral of the story is. If you experience crashes and module corruption -:
1. Close and save areas before saving the module.
2. Give your RAM time to dump, seems to improve my success rates on saves.
3. Save under a different file name.
4. Do this every hour.
5. Report this stuff to the developers.
I'm not sure of this but can any of the more technical people tell me. If I improved on the amount of RAM, would it get rid of these godawful crashes and corruption? As far as I understand there seems a direct correlation, if I have too many things open in the toolset and try to save.. BAM.. vaporised..
