I thought it is not possible to play the same deal twice. But as it occured to me, I think it is a bug.
Here is the evidence.
The 6:31 case: I joined a table after the deal was generated. Someone had left my cards, but he had not bid with them yet. So it was "my hand", not someone else's.
The 7:06 case: I joined an empty table, I was the second to join (my p as south was host). This was the Board #1.
