having some very strange issues with area boundaries used in groups.
I have tested it in RAC 2011, 2012 and 2013 and they all seem to be doing similar things.
grouping them and pasting them is fine - even between levels and even schemes. when i edit them items are excluded on sketch close and even disapear from one scheme to only apear in the scheme that i edited them in. the area still remains in both but only boundaries in one scheme.
I tried going through some similar steps in a new project, and I am not seeing what you are describing.
If you are able to reproduce this behavior in a new (small) project file, can you post it to the thread with instructions on the steps you are going through?
If you are not able to reproduce this behavior in a new project file, the following blog posting has information on tools that may help troubleshoot the project:
