So here is my reply to that.
Yes it’s true that the players modification will appear as you level up. That is working fine.
I was referring to the minigame you could play in 1.4.0 when you unlocked penetration.
If you unlocked penetration the heart button showed up on the pages of your teammembers and you could play that minigame. (see screenshots in first post.
In 1.5.9, 1.6.0 and 1.6.1 the heart button does not show up on the teammembers page, so that you can’t play the minigame anymore.
The only heart buttons that show up are the one on the player page and on the page of the queens, if you got one.
My question was, if that minigame was removed or if this is a bug, that the heart button on the teammembers page does not show up anymore to start the minigame.
