It's an odd glitch, don't know why users are effected and others not.
Maybe it has something to do with the Capcha's? Was having troubles with those a couple of days ago.
The capcha's puzzles would not solve, unabeling you to play the game. It got fixed and maybe it got messed up again with the pay-out chances.
I was able to play your glow earlier and bumped the thread, you received several players.
The tank was not effected by the glitch then.
