The proxy position updates correctly, but variable cards inserted or removed from the proxy can be deleted or duplicated. Doesn't appear to happen if you place proxy on existing interface. Can happen between different kinds of interfaces. Ex: Fluid importer with item interface attached to proxy.
The log only seems to appear when attempting to reproduce this issue on a server. However, something does happen in single player with the same setup. If you have the same setup with the proxy pointing to itself, it causes the network to stop functioning until you trigger a network update. There doesn't appear to be a message for this issue in the logs.
