I have found a way of reproducing this:

- Sit down on seat #1
- Bet 1 BTC playmoney
- Spam-click on seat #2 until you win/lose on your bet
- You will now sit on seat #2 and be teleported between seat #1 and #2.

I found a bug that constantly teleports me between seat #1 and #2 on the left blackjack table.
I don't know how this happened, but after it happened the following things happened:

- I started being teleported between seat #1 and #2, trying to place a bet on either #1 or #2 would place the bet #2 and I could only stand/hit while on seat #2.
- Another player sat down at seat #3
- Some time after the player on seat #3 leaved, I started teleporting between all 3 seats
- Placing the bet on #3 worked and placing a bet on #2 would place the bet on #3. Trying to place a bet on #1 would either place the bet on #2 or #3.
- I tried to leave my "seats", however I got teleported back to the seats again.
- This time I only teleport between seat #1 and #2.
- It is now impossible to leave the seat (maybe login out would work).

During the time I spent teleporting between multiple seats, I occupied them all, meaning no other person could sit there.
