But I think I know where the issue is with this sequence. I have created a model group that controls 10 small trees as a group. When I edit that group out I can then save.
Can there be a conflict If the group is in place and individual effects are also in place?
Moving from one version like 4.2.1 to .2, then .3, then .4 and then back to .1 would that make a mess of things?
