I recently created a realm and something really important to me is to complete the achievements, one of my friends by accidentally destroy another of my friend's chest that contained a lot of important stuff so I back up the realm 20 minutes before that happened. When we all enter we noticed that the achievements that we were completing weren't be recognize by the game and as far as I know that wasn't supposed to happened. It's worth to say that before I did replace the realm with the backup we had complete achievements and the game were recognizing them, also the problem is happening in the version 1.14.1.5 which in the section of selecting of affect version says that it doesn't exist and that when I go to edit the realm doesn't say that the players won't be able to achieve achievements.
