Thanks for your reply, I'm now backing saves up manually, and thanks for the script as well though that's probably a bit too advance for a noob like me.
The problem with objects disappearing between loads, might be related to loading different levels in the same module.
I usually have a real level and a test level where I goof around. I noticed that after I place the first new object on the real level and loaded the test level all its objects where gone.
So now I've created a new module only for test levels and I haven't had any problems yet except for some CTD, sometimes caused by the cursed objects "washing tub" and "wagon" which always makes my editor crash (even back in the classic version) when I try to place them.
