Random behavior: clone obj vs. duplicate obj.

This is really strange. I have a frame with everything this frame needs inside.

I want to copy something from another frame and paste it into my other frame. Some objects do not have duplicates, e.g. there is only one monster_somename.

Sometimes - when pasting the objects - this monster_somename is renamed to monster_somename 2 as there is already another object named monster_somename. There are some exceptions though...sometimes the pasted monster is NOT given a new name and treated as a new individual object but left as it is.

It is really random. Some objects are renamed (new objects are created), some stay...but when I paste them again into another frame it can be the other way round WITHOUT any rule. It is really random. Why?

If MMF detects that the object copied is different from the object currently on the frame it will rename it. You sure you didn't change anything after copying it? It could of course be MMF's detection that is faulty...

Also check whether some of the objects are Global?

No, no global objects. And no, nothing was changed. The pasting action is always the same...but yields different results.
