I didn't install 1.8.1 from the Welcome screen until just now.
It seems to fix pretty much all of the problems, except that all of those missing actions are still all missing. I can add them back in again now manually, but I'd rather not if your change will make that not the case.
What do you think? Should I restore from my back up and wait for the update? How long do you think that will take, btw?
