Mostly it has been that way for me as well. Except a couple of months ago I apparently did not upgrade from one particular version of Gridcoin to another in a timely enough fashion and my keys somehow disappeared (the backup I had was not valid...I think this was during a hard fork). I had to send a request to delete my beacon and had problems with that. I was out of commission as far as Gridcoin was concerned for a few weeks. It finally got resolved.

Found what the current issue is all about though: https://steemit.com/gridcoin/@jringo/gridcoin-0-magnitude-updates-here

Yeah just watch the channels and you should see any mandatory upgrades, they do try to keep them to a minimum, be on a lookout for mandatory to solve this latest issue
