Existing worlds’ world icon temporarily disappears when exiting any world.

Existing worlds’ world icon disappears when exiting any world, if you wait for a while or press the cross at the top-right corner, and press ‘play’, the existing worlds’ world icon will show up again.

There is also some lag after exiting any world, after a few seconds, it goes back to normal.

This started happening since around 1.19.30. I did not report this bug at that time.

It also happens on multiple of devices including Windows and iOS.

How to reproduce:

1. Load or create a world.

2. Press Save and Exit.

3. You can see that the existing worlds' world icon have disappeared. After a while or if you press the cross in the top right corner, and press 'Play', the existing worlds' world icon will appear again. There will also be some lag, you can solve it by doing the same steps mentioned above to fix this issue.

Observed Results: The existing worlds’ world icon disappears after exiting any world, then after a few seconds or pressing the cross button and pressing ‘Play’, it will solve the problem.

Expected Results: When exiting any world, the existing worlds’ world icon should load up quickly or immediately.
