Playing on 1.20.1

I understand it says that they need to be fed "several entire stacks" of rotten flesh, but I have given this komodo dragon over 2000 rotten flesh so far and it is still not tamed.

That's right, I also have the same problem, it won't even let me give them the rotten flesh with the left click. And when I throw the food at them it doesn't even domesticate either.

Downgrade the mod to 1.22.8

Downgrade the mod to 1.22.8

not an option for me, we're running a server on a modpack and it would be too much effort for little reward and potential bugs
