Hello fellow gamers,
Many players have been known to experience lag and freezing issues while playing this game. Recently, I found a bug which was one of the substantial reasons the lagging happened. It was related to the Mortar tower, and after fixing it, I have observed several players experiencing a lot less lag in the game. I know I'm rather late, but for many people this should fix lag issues and provide a much more enjoyable gameplay experience.
Merry Christmas, and I sincerely hope that you do not encounter any freezing issues you might have had again.
