Possibility to gain gem for any map re-completed

[Morningwarrior]

this is something that can happen if the player re plays campaign maps, fans or even his own. however this will occur with a probability, with approximately 4% chance of winning a gem if you complete the map that the player had won with 3 stars, that is 4% -1 star 6% -2 stars 8% -3 stars in more detail the player had a probability of winning a gem if he completed depending on how many stars he gets if in that game, on a map he had already ended with 3 stars
