Projectiles sometimes ignore player entities

[jtJava]

Expected behavior

Projectile is expected to hit the entity, however, occasionally goes ignores the entity.

Observed/Actual behavior

The projectile completely ignores entities.

Steps/models to reproduce

I can consistently reproduce with an arrow or fishing rod in survival mode. It was impossible for me to reproduce this while in creative mode.

Latest version of Paper with a plugin to spawn the bot (no event listeners).

I attempted to fix this by using a task to manually check if bounding box between projectile and entities overlap, and this also failed.
