Tips and Tricks
This trick only worked for the first wave of Lucky Bingo. It has been confirmed that this trick did not work with the second wave Lucky Bingo.
 * Go into the game and play Bingo as usual, after that go to Tiny Social and select Community and visit a few people. Press Home or close Tiny Social and exit the game. Open the game again and the Bingo should be in there again. (thanks for ChrisCelica in comment and summary explanation by Bruce Hee in comment)
 * Where the above failed to work, repeat the trick, but before entering the game, go into your gadget's Applications settings, look at the Running Services section, select cached processes and delete/stop the Tiny Village cache.
