I have written and received the standard response which does t help in this case. Level 4150 is impossible to win. It is required to have 48 leaf blocks uncovered and there are only 47 so it is impossible to get to the next level.
Sorry if that level is impossible but you wrote in Farm Heroes Saga Community and your game is Farm Heroes Super Saga. Don't worry we are going to move your question in the Community to help you!!!
