Send your modpack. Works fine when I test.

I'm making a battle royale style pvp minigame for me and some friends on a server.

Same issue for me plus i can't shoot while ADS sometimes.

@PMitzner Send your modpack. Works fine when I test.

You downloaded my mod from unofficial sources (a website that rehosts mods, and can potential be malicious software).
Only download from my website (mrcrayfish.com) or CurseForge. I can't confirm any issues unless you use official sources.

I can confirm, I cannot open the attachment menu normally. The menu only opens when I use the button, and left or right click. My modpack is custom (45 mods). I downloaded the mod from curseforge, version 1.2.8, 1.19.2

The menu cannot be opened even with only cgm and framework.
Update: It seems manually compiled cgm works

Should be fixed in an upcoming update. Reopen this if it doesn't work after 1.3.0 update.
