Fun, I just dont understand the AIs logic

I love canasta and find this fun to play, I just dont understand my AI partners logic sometimes. I feel it is written to avoid red canastas. For example, I just completed a game where there were six 4s melded and my partner played a two on the fours to make a black canasta and discarded a 4 while the discard pile was frozen. I get the concept of playing a card that is of the same type as one of our melded piles, because the odds of the other team having a pair of that card are slim to none, but why not make the red canasta and discard the wild card? It is maddening! This isnt the first time it has happened either. Please fix this to play for the Reds, especially when they are easily obtainable. Thank you!
