Logically, since I'm classmapping the Player class, this should conflict with the other mods doing so. These are apparently only 2 (out of 106), and should be the Astrologer mod class by ahirunomimi (for instance Attack1 won't work), as well as "Heroes of Hammerwatch Tweaks" by Giginss.

I'm requesting a damage hook to the devs so as to prevent any conflict.
