Additional context 📋
was able to reproduce in creative mode by favouriting the capture card in the server used, and able to get it from roughly enough items menu after.

I'm having the same issue but in a singleplayer world on Fabric.
I also tried to put the ender dragon card in a tier 2 plains mob farm.
Sadly I made no backups and am currently unable to get into my world.

If you let me know which Minecraft version you're using, I can provide a quick fix.
A proper solution that correctly renders the Ender Dragon will take a bit more time.

I'm playing on minecraft version 1.21.4 with easy mob farm on version 9.7.0.
Thank you in advance :)

I’ve released a quick fix as version 9.7.1 for 1.21.4, which should be available within the next few minutes. It should allow your world to load again.

However, please note that Ender Dragons currently don’t drop anything, this is intentional in the current design and will be addressed properly in an upcoming update.

Thanks again for your patience!

@MarkusBordihn I can load my world again with the new version. Thank you very much :)
