After 2.0.20(build 80511) update.
Mod load failed when start game.
The error message is 【File __base__/graphics/icons/shortcut-toolbar/mip/alt-mode-x32.png not found】

-----11/20-----
Solve solution before mod update：
In folder Factorio\data\base\graphics\icons\shortcut-toolbar\mip
Copy alt-mode-x56.png and resize/rename to alt-mode-x32.png.

Check Factorio\data\base\graphics\icons\shortcut-toolbar\mip folder
There are only alt-mode-x24.png and alt-mode-x56.png
No alt-mode-x32.png in 2.0.20

Same issue started appearing

Same issue

If I copy alt-mode-x56.png and resize/rename to alt-mode-x32.png.
Factorio will load mod success.
