Cannot pass PlayerInteractEvent to SuperCraftBros

[jwflory]

This was something I originally encountered in v1.3.1, but I wanted to update to v1.3.3 and see if it was still a problem - as of the current commits, this stacktrace is fired on what appears to be every time a player is hit by another player.

It's worth noting that this doesn't appear to have a direct impact on gameplay among players.
