Qedibh Meat Master won't take meat.

[Egon the Monkey]

I had Magma Lizard meat, but you can't turn it in if you have it. There's no dialogue option.

[Mushroom Mushroom]

The meat is tagged as stone lizard meat when you harvest it, btw.

He took the meat from someone in our party who wasn't level 8 or above, so it may be linked to level now (similar to rat tails?)
