Description

Basically, the mod does not do anything. If I recall correctly there were issues like this in earlier Minecraft versions that were resolved and closed, so I can't really explain why this is happening, but it is. The other mods I'm using Advancement Screenshot with are listed below. I tried enabling and again disabling the option to show the screenshot message in chat, it did not change anything. I added Mod Menu to confirm that the game actually recognized the mod, and it did, but it continued to not work, so I removed it. I was also using the BlazeAndCave's advancements datapack, which i removed, and it did not work for vanilla advancements either.

Thanks for opening the issue! The mixin triggering the screenshot no longer worked in 1.20 due to parameter changes. I missed that when updating, apologies. This has been fixed in version 4.2 of Advancement Screenshot.
