What is happening:
The v 2021.04.01 update has added some new main menu themes made by players in addition to 2 official main menu backgrounds. But the latest v 2021.04.02 update is somehow missing all of them (including even one of the official menu backgrounds), with only one official main menu theme left.

What should be happening:
All the main menu backgrounds should be used when player is launching the game and sees the main menu.

Steps to reproduce the issue:
Just launch the game and look at main menu background.

Game client version:
Latest update v 2021.04.02, desktop client
