which mod is this from bi-bio-cannon

I seem to recall it being from bio industries but I won't be able to check properly until tomorrow

Ill check.

accidently fixed. I had to exclude items where the minable item was not the same as the entity name.
will look at this later but the darts work

Awesome, I'll load it up again soon and confirm

All good now, thanks :)
