BUG #1: After using a Cellular Shopper, I was mashing and ended up getting two items (I only had one Cellular Shopper and that was it). After that, it wouldn't let me roll. More info later.
BUG(?) #2: When a shop is stolen from in Koopa's Tycoon Town, they can steal from the player who activated the happening space. Not sure if this is intentional or not...
BUG #3: Was playing Bunny Belt and ended up tying. Despite Knight not participating in the duel (it was between P2 and P4, Knight was P1, turn order was port order), it said Knight won and gave him the reward. I laughed out loud when seeing this, but it's absolutely a bug. (this was before the update)
Bit of info on bug 1: The item I bought was a reverse mushroom(?) (it was a 10 coin item) and I had around 22 coins (just enough to buy two of them)
