Hi,
I found small bug.
I will try to explain.
Let's say I have 3 objects in geometry list - M1, M2, M3. I populate objects manually in custom edit mode. And I made all items to be M2.
If I remove M1 from the geometry list - all items become M3.
So forest do not keep link to M2. It just thinks all models are number 2 from the list.
Thanks.
