Hmm odd. When I was doing the prior fix for you I honestly EXPECTED that error but didn’t get it haha… I get it now. There’s no real issue here - basically Newtonian is just trying to look for changes in momentum on a dead character. It won’t break anything, just give some errors. I’m still incredibly ill, so I’ll have to ask a little patience. In the meantime, there’s no reason you can’t just continue to use it - the errors will only occur in the time between your character dying and them respawning and are basically just warnings 
I will have a fix for you, and Newtonian in general, as soon as I can manage it
Ah okay. This comes down to how Easy Ballistics is designed more than anything. It is designed with realism in mind, and obviously the speed of the bullet, IRL, is what causes the damage. In order to utilise the database information to control weapon damage, you would need to parse the values through to EB and override the damage on impact. Again, I’m more than happy to assist here, I’m just not currently in a great state to be putting my head into UE4 haha. Hope you understand and don’t mind a short delay. This virus has been very annoying -.-
