I can confirm this, and not only since beta. I have this issue on 1.4.2, too. To reproduce it, close the game, reopen it, and go to Global Textures. All of those have been reset, and I have to manually add them back. It mostly happens when I close the game when I am playing on a world, and closing it from the main menu doesn't seem to cause this issue. Still, it sometimes happens
