Divines went missing in stash

Okay so I know I'm not crazy but i was doing an exchange for orbs of chance for exalts and i clearly know that was the case...6 orbs of chance for 42 exalts and i clearly seen the rate when i accepted it. As i continued and was looking at my stash and about to run a map several minutes after the exchange i noticed my divines went form 8 to 2 in my stash....Whatever bug this is, is not cool i don't get to play as much as most and this currency i value especially for the time it took to acquire it and now its just gone. This CANNOT happen and I hope GGG you can fix this!!

I will mention that if i misread an exchange the game will inform me of an unfavorable exchange so i couldn't of possibly traded 6 div for 6 orbs of chance

So if not a bug can anyone tell me how this happens? Please

Yeah, a bug... If it makes you feel better, let's call it that... Definitely not you misreading a merchant buyout...
