Some player has more than 24h ingame but still haven’t gotten the achievement, so i think this guide might help yall.
Check the in-game statistic.
All you need to do is check your “in-game” statistic.
Launch the game ==> Game setting ==> Statistic ==> check the “Chill time” to see how many time you need left.
After you have enough 24 hours, you will get the achivement.
Hope this little guide can help you.
Thanks to Little_Cutie for his great guide on how to get the hard working achievement, all credit to his effort. you can also read the original guide from Steam Community. enjoy the game.
thank you
