Unable to power down (ERROR: Transaction broadcast error.) Anybody have this?

I get Hive is a new technology and all but I mean it's been around for long enough to not have to deal with such errors, no?

Just frustrating that I can't solve this problem and have to dig into random posts of people having the same problem. Can't someone create an FAQ with the solution to this problem at least?

I've tried to power down multiple times with this error. It's things like this which keeps people away from Hive. It's complicated enough to to deal with the whole range of keys but to have issues like this too just adds so much extra headache.
