I lost the ability to earn achievements in my survival world after a bug that told me to unlock the full game even though I've had the game for nearly three years. Initially, I was unaware of this issue, and started playing on my survival world offline when I noticed I was getting instructions like "Use W A S D keys to move" and similar just above my hotbar.

After this, I opened up the game menu and it said that the remaining trial time was expired and there was another button that told me to unlock the full game. I then pressed "Save & Quit", went back to the main menu, and again- in place of the marketplace button at the bottom- there was another "Unlock Full Game" (or something like that) button. I tried going on another world in which achievements were obtainable, but the same thing happened. I thought that maybe being offline was the issue but before I closed the game, I checked the details of my survival world and unfortunately saw the "Achievements cannot be earned in this world" sign.

After coming online as soon as possible, I gave it another shot. The game worked as usual when I had an internet connection this time. The marketplace button was there, and so was the "Sign In" button on the far left, and I of course signed in first. However, I checked the details of my survival world and other world and the same sign- "Achievements cannot be earned in this world" appeared. My game is working perfectly fine now but now those two worlds cannot have achievements anymore. I am especially concerned about the survival world as I spent much time and effort on it.

Is there any way to make it so that I can earn achievements in this world again? If there is, I would be extremely thankful.
