I’m not sure what happened, but i just lost half of the objects from a complete apartment layout. Here’s what I did:

- Duplicated 1 object (a dimension line)
- Moved the dimension line around a few times & decided to undo some of the moves
- performed one undo, and waited while each object in the layout was re-drawn
-un-checked ‘objects’ under the 2D button so the next undos would be quicker, and performed another couple undos
- re-checked ‘objects’, noticed that 1/2 of my objects did not reappear
- logged out, & logged back in. objects are still not there.

- i did not multi-select any objects at any time
- i did not hit delete at any time
- i did not save any changes, and this whole process took less than 3 minutes, so I’d be surprised if autosave kicked in.

Is there any way to revert to an earlier version of my layout (from say, yesterday or this morning?) this is really frustrating b/c it took me an extended amount of time to measure all of the objects in my apt, and i’m hesitant to do it all over again & risk losing my work again.

Any help would be greatly appreciated, Thanks so much.
