Pets and ExpBalls

I have a sort of odd problem, for some reason random pets won't use special expballs unless their mete_level is set to 25500000. But this only happens to one players account. Other people can compose just fine and use expballs on thier pets, but this one player can't get special exp balls to work on any pets. Any idea what might cause it or how to fix it?

I did check that exp_type is set to 1 in itemtype and it is, but like I said, the same kind of pet will use special expballs for other players, but for this one persons account, they wont.

We have also tried leveling the pet manually, then composing it, but it still won't use Special expballs.

Thanks for any help, I know its an odd question.

It's probably not the account but the actual pet. Try trading it to another person and test to confirm. At that point, you will know whether to concentrate on the pet or the account. ;)

I will try that, but the only thing is it happens to every pet that this player hatches.
