On doing some more testing, I may have mis-diagnosed the problem.
What may actually be happening is this: specifically to bot games, my ear is expecting a sound to play indicating that it is my turn, but the sound does not play.
Contrary to what I thought, it doesn't seem that reloading makes it play again. So, it may just be that bot games do not have this sound. I thought they used to have it, but I may be wrong.
