So I bought 2 $50 Heroes chests over the past week or two. I know... it's a lot of money. Well, I got 2 duplicate tanks (the same tank in both sets of chests I bought). I got the Bog Horror twice which I already owned. I was refunded 6300 gold instead of 9000.
I opened a ticket thinking I wasn't credited properly, support said compensation was only 6300 gold though because they are on sale right now. The web page ought to be updated to be clearer. Don't get me wrong, I'm grateful for the gold refund, I was just expecting\thinking it was the full price refund in gold.

"If you receive a Premium tank you already own, you will get a full refund on its Gold value."
to something like "If you receive a Premium tank you already own, you will get a full refund on its currently listed Gold value."
