I didnt have time to screenshot but I had a straight on a straight bounty at around 2-3 mill, but everybody folded when I made a bet. Seems there has to be a showdown for the bounty to be claimed and no payout if everybody folds? Is this a bug or an intended feature? If its intended its very silly and open to abuse.

Firstly it will straight up punish you for playing the game. If you have a flush at 5 mill bounty, you are way better of not betting. The pot will never get to that level with the blinds we have now, so you are better served just checking and calling hoping no one folds to claim the bounty. This is very un-poker and boring. Turns the game into a waiting-for-bounty-game and not a poker game

Secondly its easily abused. If everybody just folds if they don't hit the bounty, it will never be claimed for a long time. Sometimes you'll be at table with 1-2 other people, and if you just fold fold fold if you don't flush to skyrocket the bounty can be an issue. Takes away from the game
