We have pushed a ton of stability fixes recently, and we now have a stable release channel which we release to monthly (see https://flynn.io/docs/stability https://flynn.io/docs/stability). I highly suspect many of the bugs you encountered have been fixed, and we make it a priority to investigate and fix reported bugs as quickly as possible, so if you end up giving Flynn a try again let us know if you have issues and we'll fix them. As for updating, the in-place updater still has some kinks but the backup / restore route is fully tested and is reliable (see https://flynn.io/docs/production#updating https://flynn.io/docs/production#updating).
