Error only fires when I punch a butterfly from... familiar fauna.

This was fixed on Familiar Fauna's end (Butterflies had a health value of 0.5D before, so I'm assuming converting that to an integer was making it negative?), although you should probably add some kind of additional check to make sure this doesn't happen in the future with any other mods.

Should have never implemented the summoning thing alpha into the build. :/ Sorry for the inconveniences. Will do a check on my end for later builds

Fixed for next update because the summoning stuff will be gone; also fixed it in my backup code anyway if I ever want to use it.
