I'm collecting info on drop chances for each chest in the game, so today I noticed I had enough gold to buy a chest. But when I clicked on the chest shop (in MP) I saw this: Those are the two items I got from the last chest I purchased (an ornate). I may have quit the game back then without clicking the red button (this was probably a week or so ago). And that purchase may have been from Anjin not MP. No idea where "5 random items" is coming from.
Yes, unless you click Take All and Reset, those items you get from the chest just stay there forever, talk about quality service! But the 5 random items pops up when you do this, and i personally don't know why this happens. Perhaps a piece of code from old chests that gave 5 random items?
It's chest reset visual bug that happens whenever you leave and re-enter and is reproducible in another way with the new party retrieve/store feature. http://www.cardhunter.com/forum/threads/chest-shops-not-resetting-correctly.1483/#post-18236
