Whenever i shoot a gun from this mod the bullets simply despawn before even getting far away enough to deal damage making all guns completely useless with the excaption of the flamethrower which doesnt disappear but instead spawns the flames inside you setting yourself on fire instead of your foe

what exactly do you mean by log? its not like id have any crash logs since you know... it doesnt crash it just plain doesnt work

Bullets spawn spawn small and size up after a tick.

they legit dont even fire my guy... i can aim at a mob and shoot but nothing happens besides a muzzle flash the bullets dont come out and i do no damage

Works here in both dev and built. No log no help

ok ive come to the conclusion that its not just your mod thats doing this... its all mods that adds item/projectile entities but im still no closer to figuring out the culprit

Do you have a list of your mods?

I don't see anything sticking out so I would suggest the old school method of removing mods in chunks until the issue is gone then adding the last bit of removed mods in one at time until the issue reappears. As this would be another mod causing the issue with any custom projectiles, I will be closing this issue but leaving comments open in the event that you discover what is breaking projectiles.
