Issue Description:

Issue only seems to happen when using a projectile to kill a mob.
Melee doesn't trigger the crash.
Vanilla bow doesn't seem to trigger the issue though but most other projectiles do.

What happens:

Game crashes when killing a mob with most projectile types.

What you expected to happen:

The mob to die without it crashing the game

Steps to reproduce:

Have you disabled half of Tinkers?

Removing Tinkers fixes the issue, disabling the modules of tinkers however did not.
Next thing i could try is installing the separate ender io modules except for the tinker integration one?

I think I see what's the issue. Do you have "TinkerModifiers" pulse disabled? If yes, I know what to do.

(I mean, the getBehadingLevel in the stack trace may be a hint for why it's crashing here... ;) )

I'm afraid i don't know how to even disable "TinkerModifiers". How do i check?

Not sure. But let's make this easier for both of us: Just install the next dev build of Ender IO ( https://ci.tterrag.com/job/EnderIO-Modules/job/EnderIO-Hourly/ Build 948) when it's ready. If that helps, then I diagnosed the issue correctly.

Will do, will keep you posted when i test it.

Issue seems to be fixed. Tested with multiple types of projectiles and no crash.
I appreciate the quick replies and help, cheers mate.
