I recently made a 1.7.10 server with the mod Advent of Ascension. The mod adds a lot of things, including new weapons. Oddly, when I try to attack players with these weapons, they are not hit. No knockback, sound effect, or damage. The regular swords from the mod work fine, but the Greatblades, Staves and Energy Guns do not work. Any help? I have checked the config and seen no obvious fix.
