The Enhanced Edition seems to (oddly) have several old bugs that (I thought) were eliminated through patches in the original release.
For example, people on Steam are stating that health bars aren't syncing properly between multiple clients in co-op, possibly because of stat-modifying equipment. Wasn't this fixed back in the day?
Also, people on Steam are complaining about that old bug where melee characters need 1 extra AP to execute a melee attack than is actually required or used (i.e. the game claims Madora's attack takes 5 AP when it's only supposed to use 4, and it will only use 4 when the attack is executed, but it will not allow you to execute it unless you have 5 AP stored up). Wasn't this also fixed a long time ago?
