Nope, that sounds perfectly fine. There is really no reason for one or two
servers to behave differently.
One scenario that I could imagine causing the behavior: I assume your NodeCore
is derived from Geometry. If you call beginEdit on it without setting a mask,
the inherited parts will be transfered, too, which would overwrite the changes
made on the server and remove the created geometry. Can you try setting the
fieldmasks for begin/endEdit and see if that makes a difference?
