Hello, I love this app, thank you so much for developing it! I hope it is alright to report this in English, my German is very bad :/
I would like to report a bug I encountered today. Near the end of the round I only had a bomb and a pair left. I played the bomb and while the bomb animation was playing I tapped on the two cards of my remaining pair to get ready to play them and finish. When I did, both cards raised up out of the hand as though they were both selected, but one of them was offset to the left a bit as though it were part of a larger set. When the timer finished and I played the selected cards, though, only one of the two cards actually got played as a single, which ruined a guaranteed finish.
I'm not complaining about the outcome - I should have verified my selection when it was clear that there was at least a visual bug happening - but it might be worth looking into this scenario. I assume the problem was somehow due to my pre-selecting my next play during the bomb animation.
The attached image is my hand when the bug occurred and the red outlines are where the two 9s appeared after selecting them but before playing them.
Thank you again for this great app!
