I am wondering if anyone knows if this is supposed to be part of the dragon or if it is a bug with the dragon.

I have a dragon that can carry 18k weight and tested an anky with 500 weight holding 1800 weight in it's inventory. I used the dragon to pick up the anky thinking the weight on the dragon would jump to 1800 ... it didn't it stayed at just at 700 weight.

So wondering if that is PART of the dragon or a bug..
