By "use the Full Name", what are you actually doing. Also, how are things mapped out?
Keep in mind, Alias goes through the NameMapping engine to identify objects. There may be things like "Extended Find" turned on to help find an object that may not be a direct child.
Generally speaking... it sounds like you have object identification issues. I'd start going through your NameMapping tree and seeing if you need to clean up or correct some improperly identified objects. I'd start with what is mapped as ContainerLeft, check what properties are defined on that object in your mapping, correct them if need be. Then, I'd start looking at the parent objects in your NameMapping tree to see if they need to be adjusted as well.
One thing to be aware of... you should NOT be using FullName as a property for NameMapping... it defeats the purpose of NameMapping by bypassing the engine completely. If your objects are using FullName, find an alternative.
