Dang noobs
generally if data is updated automagically with no DynamicData assigned to the object, the object name is what the client uses to make that linkage, and often the entire nesting structure above that object has to remain the same. Even when the name of an object doesn't seam to have any significance, the client expects an object of that name to be in a specific path to recieve the data. In many cases breaking the expected path will in fact cause client crashes. The client tries to pipe data to some object that isn't where it expects to find it and an error is thrown that SOE never expected.
As a general rule, try not to rename stuff already in the default UI. If you do, be sure to test to see if that broke any hardcoded functionality.
