Splinter Cell

Yesterday I took charge of the monkey. The one on my back. I had only one of the bonus levels of “Splinter Cell” left and I decided it was going down. So I play it, and everything is going great. I’m sneaking past the bad guys. I’m forcing subs to surface. I’m breaking into secure installations. And I see the end in sight. There is the sub that I have to get to. When I get there, the level is over, and I’m free.
Except for the invisible wall blocking the way.
I checked on the web. There is a glitch on the level that sometimes causes the wall. The workaround, I read, was to restart the level. This is an online level, you think they could have fixed that easily enough. Now I don’t have the catharsis of finishing this time-suck.
That was the last level I had left. Good enough. Stick a fork in it, I’m done.
