ingame shop bug

usually happens at least once every match to me, I haven't tied down any possible causes, but sometimes when I go to shop, it will show a lower amount of gold on the shop window vs outside of it and i won't even be able to buy the item that I can afford, couple seconds go by and it will fix itself.

to me this seems like nonsense, because Never should the shop window vs outside of it show different gold, your gold stash is your gold stash and the display of it should be the same whether in or out of shop window. please stop intentionally adding bugs into the game :D pls
