Hey, long time no see!

There have been similar issues that other players have mentioned to me as well, mostly on IOS. I have had the 'buttons disappearing' thing happen in relation to building a house in "Editor Mode" on PC, and also with the Bounty Box. If you log out while carrying the Bounty Box behind you, your action buttons all vanish and you can't change them in the menu even if you drop the box upon logging in again. This particular glitch can be fixed if you drop the box (press the 'box' button, then 'drop' after reviewing bounty information) and then restart your game. I haven't personally had those health issues, but others definitely have in the last couple weeks.
