If it affects other games, I can see that you would want to know the reason right away, but my point is that on the game in question, you had bet the $250 max and inquired if you could bet more and were told you could not. At that point, you can't really expect anything to change as far as that game is concerned, yes you are used to them removing the circle a couple hours prior to game time, but for whatever reason they didn't remove it nor were they planning on removing it (If they were planning on removing it, I would certainly hope the CS response to be that you just had to wait until closer to game time when they would remove it, so them telling you that you can't bet more finalizes it in my mind).
Still not sure if I got my point across, since I tend to confuse more often than not when I try to explain things, but basically I wouldn't expect you finding out why the game is circled to change the fact that for whatever reason they're limiting the maximum bet on that game.
