Objects disappearing in Max 2013

[Morne]

Hi all

A colleague has experienced random objects disappearing randomly. Asif it gets deleted. Its nowhere to be found in the scene. 1 Minute they're there, next minute not. Undo doesnt help. Only thing that helps is to reload previous saved file (providing you noticed in time and didnt save over it)

Now I'm also experiencing this for the 1st time after months of little to no problems. It's a different scene to my co-worker and our hardware specs are also different. Also, I'm on straight max and he is on max design.

Weird, and ANNOYING!

Is it possible that it's only invisible in the viewports? If you switch to e.g. DirectX, does the issue go away?

Best regards,

no, if you go into object list (press "H"), its not even in the list, its just gone

It could be the slate material bug (where you hit delete on a material but it deletes your selected object) but I'm pretty sure they've fixed this? Plus you'd notice that your materials weren't deleting...

The only other thing I can thing of is version incompatibility. I don't know what the differences between Max and Design but could it be a modifier/object that's present in one version but not the other?

no it's a different scene we were working on that's not related. He was on max design and me just max.

Although now that I think about it, my co-worker did originally create the scene I'm working on now. I never had this issue before now.
