Weird problem with MTA Map Editor

[Darius]

Now i've some really weird problem with MTA Map Editor. When al be there editing away on a map, al complete what i'm doing then save.

What i've noticed though is that for some reason, the latest save stuff i've done is there. But the last stuff I did before that has been deleted, or maybe even 'replaced'. Like I did a bunch flowerpots in this restaraunt, and now they are gone. So i'm going to have to do that all again even though I saved it. Really don't know whats going on.
