CardGames.io review: Had 13 cards in his hand, threw 15 and had 2 left in his hand

At first, I thought I was seeing a lot of things when playing Canasta until I began to write down what I was experiencing. One game in particular, Mike had 13 cards in his hand but melded a total of 15 cards and still had 2 remaining in his hand.
I also noticed and kept a record of the shenanigans. Most games, during round 3 or 4, Mike and Lisa would receive 3 of the 4 Jokers and a majority of 2 wild cards. However, in one game I received 2 jokers and 6 2 wild cards. I couldn't do anything. Typically, during these rounds the Mike and Lisa would win every time.
