I was just playing level 1840. I passed the level. I had earned a level reward, so as soon as I finished the level, the prize box showed up. After getting the rewards for that, instead of going back to the map as usual & then receiving the map reward before moving onto the next chapter, like usual, the map just shifted & brought me to level 1841 without getting anything. This is especially significant as I am currenty playing with a timed booster & only a few pieces away from another. Had I received my map reward I would have most likely had 2 that I could play in tandem, instead of just the one. It really sucks, because I used extra effort & a bunch of lollipops to beat the level, knowing this would happen. (Activating the 2nd booster via map reward) Honestly, even if this gets "fixed" most likely, the one I have will have run out & then I'll get the other 1 & only be able to use 1 at a time.
My game ID is 3103166343.
I'm currently playing on Windows 10.
