There might be 2 different problems. Either there is too many notification form server and client was out of sync (this status not yet mooed to new UI) or there is something bad happening with server.
If objects are just out of sync you can drag and drop object (it should work), then close and reopen console again - if objects are properly moved after re-login - then it's just synchronization problem. If they are not - then there are some delays on the server side, chat can be investigated further more.
