(I'm posting on Ransom's behalf since she is too busy to do it herself.)
http://www.seibertron.com/heavymetalwar/view_arena.php?arena_id=74133 -- When the fight reaches the time limit, a win is based on % health left, right? So even though both TFs had same amount left, why did Celerity lose when he got the opponent down to that level of hp first? Is that a glitch, or a misunderstanding on our part?
http://www.seibertron.com/heavymetalwar/view_arena.php?arena_id=74136 -- Says that the Predacons won, but Overbite is a Decepticon. As such, I have no way of knowing if Mizu lost this fight or not. (She'd better not have lost, is all I can say at this point.)
Edit: I forgot to mention that the arena battles aren't displaying on the HMW index. Currently, you have to go straight to your characters' bio page.
Edit redux: Not a glitch, but the alt text for this alt-mode

needs fixing. Currently has a mispelled word.
