When trying set an Auto Switching Item, if you scroll down and render some Create Mod items, the game simply crash. So if you want to set any items that are located below the Create Mod items, you will have to remove the Create Mod, set the desired items, restart the game and put the Create Mod back on.

Here's the crash report: https://pastebin.com/1CPmDNbW
