I wasn't aware of this bug until lakeshow7 brought it up to me.
If your game crashes when the player shoots and is fouled.(ex. lamar odom,Michael Redd) it has to do with their freethrow ritual designation.
I found that when I replaced the default aiact with another one , any player with the freethrow ritual set with the number 1 will crash when fouled. The solution is to change the 1 to just a blank space.
