Hey there,
my HUD placement is screwed on PokerStars Spin & Go tables. I think it's due to HM2 interpreting the table size as 4-handed where in reality it's a 3-handed game. It might be that technically they are 4-handed tables where one player just is missing from the start.
However, what this results in is the HUD-panels randomly showing up in wrong places. Sometimes the player to your right is considered to be sitting on seat x, while other times it's considered to be sitting on seat y. I tried setting a preferred seat but that didn't help at all.
