This bug works with all versions of the game for IOS. The bug is when my brothers iphone 4 joins my LAN on my iphone 4, we get MASSIVE server lag and it lags out on us and then when we join again, the blocks we created/placed wouldnt be there or they would only be there by the player who put them there...
ex: my brother puts down dirt to fill up water and i come by look at the progress. I dont see him placing blocks and he sees me going through blocks and i sufficate in the blocks by being trapped.it also happens on my ipad 2 so i dont know if its the IOS or the game. We tried to uninstall and re install the game with the same results. it might also be my brothers phone becuase we had trouble setting up his phone when he got it. I do not have a picture and i hope this is detailed enough...
