Several times I've found that, if I play a game in the arcade for too long, than when the game ends I can not submit my score. I am shown a message telling me I should access the game from the DP site, and can't go to it directly (I'm paraphrasing here). I then need to re-login to the DP forums.
I'm speculating this is because once I leave the forum for a preset time period, my session is logged out. THEN, when the game ends, I'm no longer logged in and therefore can't submit my score.
Is this a known problem ?
Does it even happen to anyone else ? I'm surprised I've never seen it mentioned previously.
