Some feedback: CTRL + space on Chrome 49 seems to be the hotkey for "We're still a bit buggy and hit a wall. We've reported the error and disabled the editor to prevent data loss.". Actually now pretty much anything I do brings up that message plus: vendor-6d85b06….js:31 Uncaught Error: opAcknowledged called from a null state. This should never happen.
