Esther wants a Magical Pear Tree. The tree and seed go for 40M+ in shops, and from the googling I did, neither is in shops, making it retired. Is she supposed to ask for it or am I really expected to shell out that much for a few Vesnali Coins?

I wouldn't call it a bug, it should probably be excluded just on the price, but it probably just falls under the type of items she can ask for. You can just quit the quest and hope for a better one next time.

The reward is 25 coins, so don't do that one unless you've got the seed to grow it.

comments under the News post by staff say that they will contact the programmers and make sure that items asked for from now on will be restockable. It was not their intention that Esther ask for items so expensive.

They can't fix the one you're on now, though. You should quit it like says.

That's good, I usually don't read the news comments because they tend to be a lot of the same stuff. I went ahead and quit it, hopefully I'll get a better one.
