The following stacktraces were produced when a user on our server right-clicked an EnderIO conduit with a chisel:

Let me know if you need any additional information.

The stack trace says it was a left click, and this seems to be caused by either EIO or sponge (can't tell which) putting a null hitVec into the event.

OK, I'll redirect this to either repo then, Thanks for the info.
