something went wrong with a trade on my account ( pjottrr)

i wanted to sell    872689 KARM
it sold immediately for 6 staoshi
however, there were only 616694.99320116 KARM sold

somewhere 256k karma went missing because it is not visable as an order, in the trade history , and also no ballance that would clarify this .

Can you clarify / look into it?
