What are you learning from my game?

Hi everyone!

This is my first time playing Stardew Valley, so I'm still learning how everything works and discovering things as I go.

I was working on the Community Center and only had the Greenhouse left to complete. Since it was already Winter of Year 2 and I wouldn't be able to finish it in time, I decided to buy a Joja Membership so I could get the Greenhouse.

After some time, the Movie Theater appeared normally. However, after I closed the game and opened it again later, the Movie Theater was gone and the Joja building had returned.

I'm playing on mobile and using the latest version of the game.

Is this a known bug? Has anyone experienced something similar or knows what might have happened?

Thanks in advance for any help! Since this is my first playthrough, I'm not sure if I did something wrong or if this is actually a bug. 😅
