I was trading the money I had from my seller to my main account. The total amount on the seller was 21,208,102. I traded with my main and put in 21kk for the amount, leaving 208,102 on the seller. As soon as I hit "Accept" on both of the trades, somebody bought a KylinGem from me for 350k. For some reason I never received the 350k that I was supposed to receive for the KylinGem. My seller still only has 208k on it.
Yes, I'm positive somebody bought it because it isn't in my shop nor in my inventory, and I saw the red text saying somebody bought it
Yes, I'm sure I didn't "accidentally" mistake the amount of gold on the character at the time.
