This game is just riddled with bugs. After experiencing those crashes in GOG Galaxy, I decided to only play Ranked on Android, but I'm still getting swindled out of my mosaic pieces. Although this is unrelated to the previous issue, earlier today, the Ranked matchmaking was taking a while, so I decided to back out, but as soon as I hit the button, the game told me that I had finally found an opponent. After waiting for the screen to transition into a match for several minutes, I decided the game had likely froze, so I restarted the app. Lo and behold, when I got back into the game, I was missing a mosaic piece, so it seems to have credited me with a loss despite the problem being with their servers/programming. The crazy thing is that my internet is fantastic; I've never actually been disconnected from a match.
