It had been explained in the LB thread that the cherry trees were purposly given to android devices as they had serious bugs and issues which held up their play progress during a timed event. Whoever had this bug, received the cherry trees.
The rare gold rune drops are the same for all.. those who have obtained more Gold Runes in order to obtain Rainbow Alis have done many more exchanges or spent gems of their personal choice. I have seen a couple of Mystic Kilns, and know they were paid for.
It's the Elves that are mean to all.. asking outragious exchanges.. returning a misery for expensive stuff, but does this to all. I do think the appearance of gold runes have to do with the total amount of exchanges you have made, but not to crash the kingdoms ability.. I do only comfortable exchanges, easy to replace, that way I'm not sorry about any loss.
