Issue description

When you summon a bullet, it just falls to the ground and makes a dirt block-breaking noise. But if it hits a mob, the entire game crashes, and the world is now hard locked with the game crashing every time I try to get into it. After looking through the crash log, the most likely reason is that since there is no "shooter" (since the bullet was summoned rather than shot), the game doesn't know who shot the bullet which crashes the game. I'm basing this off the main error which says the "shooter" is null

This seems to be the main error: java.lang.NullPointerException: Cannot invoke "net.minecraft.class_1297.method_5781()" because "shooter" is null

I don't think this is a high-priority issue since you need commands to summon a bullet but it still crashes the game which probably makes it a bug.

Steps to reproduce (if reproducing the issue requires exact steps)

1. Summon a bullet on top of a mob
2. Crash
