Weird problem with MTA Map Editor

[Chillosophy]

For fucks sake, I've got this problem too. Keeps happening at my latest map, and I have no idea why. Two hours well spend

Code:

    <object />
    <object />
    <object />
    <object />
    <object />
    <object />
    <object />
    <object />
    <object />

Welcome to the club. Btw if you have that where its all gone, then your fucked. Gonna have to start it all over. And don't worry I share your pain. Had it happened to me 4 times.

What I do is make multiple saves, and even copypaste the files to different locations. Sometimes it wipes all of the saves (only the saves of the current map tho, not like saves of different maps)
