There's a couple of issues on the Battle Coliseum Guide page: https://subeta.net/games/battle/battleguide.php

1: Under "Where is the healer, battle coliseum, battle quests, secluded shrine?" the link the secluded shrine is messed up and goes to a blank page.

2: The link under "Weapon Guide" is messed up and makes all the rest of the text on the page into a link.
