Lost of 5b Kinahs after doing Tahabata Run

For some reason after being killed by Tahabata dragon and respawn in Heiron, when I was checking my inventory, I saw that almost 5b Kinahs where taken from my inventory and I didn't bought anything after Tahabata. The only thing I bought was a Ring (check my account history if you wish). But after the buying it was like 5.8 Kinahs left..and now I have xx millions. Is there a way to check the history of transactions in my account to see where is the flow or my mistake? Thanks in advance.
