Description just says 'You were agreeable'. Played through 3 times now and not got it... anyone help please?

I started the game late last night, played for 30 minutes or so then needed to save/quit but couldn't find an option to do so. The 'logout' option in the bottom right corner says that progress won't be saved... ended up just leaving it running which isn't ideal!...

Was the Thawful joke supposed to unlock this achievement or is there another hidden joke?

Trying to start the game and every time i try steam stops responding, i waited nearly 10 minutes for the game to start but it looks like steam completely locks up when i try. as well i tried opening the game from the windows shell and the shell froze up too. is anyone else having this problem?...

I couldn't quit the game, the log out button does nothing (I had to Alt-Tab an close the application manually). Using linux (Fedora 23).
