Level 3762 was a money grab and I decided to pony up and buy my bank. I was very careful to wait until I was close to completion before using my coins. When I was at a close enough score, I used 10 coins to "play on.' Needing only a few more colors, I had to buy the extra moves and stripe/wrap for 16 more coins. I completed that game with those extras. A few levels onward, I needed one more move and knowing I should have plenty of coins, attempted to buy a few moves, but I have only 6 coins!!! What happened?
