I noticed today that crown balances on Steam accounts are visible to everyone if the player's inventory is public. I thought crown balances were supposed to be private? I mean, it even says, "This amount is private and shown only to you." So I assume this is a bug. And IIRC, it was not like this in the past.
My Steam inventory is private, and I'd rather not link directly to other players' inventories. Basically, just check any SK player's public Steam inventory and type 'crown' in the search box, and you will see their balance.
I should also note that energy balances on Steam seem to be outdated/inaccurate when I try to send a trade offer. Normal Steam trades seem to work okay. (Steam trades and trade offers are slightly different.)
