I updated the mod's version to v9.3 and then my custom crosshairs were all lost. I spent a lot of time making them at the time, but now they're all gone. I don't know why.

minecraft version:1.21
fabric version:0.16.10
mod version:9.3
(And this version of minecraft of mine has also added many mods!)

To add up, none of these custom crosshairs have disappeared. They are all saved in the config folder, but they are not displayed in the game.

What version did you update from? What is the file name of the crosshairs that exist in the config folder?
