About 10-15 minutes ago, I went to the homepage and went to Tiny Tanks (game ID 15699) on Google Chrome. When I saw keyboard controls, I prepared to change browsers due to Chrome's keyboard-press lag, but I figured I'd at least try it. I went to the tutorial, and it worked fine at first, but the lag started to come later when more stuff was added to the level I was in. So I quit the game and went to IE (my other browser; it's inferior, but it does not have keyboard-press lag and is therefore better for keyboard-based games). However, when I tried to click it, I got redirected to the homepage. So I went back to Chrome, and the same thing happened.
Based on what I know, the redirect occurs when an unused game ID is attempted. I therefore conclude the following:
Tiny Tanks (game ID 15699) has been deleted, but the homepage has not updated to reflect this deletion. If the game is not deleted, then why did I get a redirect on subsequent tries?
