Regions occasionally stop sending entities to the player

[codeHusky]

Expected behavior

Items from broken trees, as well as mobs and other entities, should be properly tracked and send to the Player's client so they can be displayed.

Observed/Actual behavior

Occasionally, regions will stop sending these entities to players, resulting in a confusing desync where you can pick up items but never see them on the game / hear them get picked up.

Steps/models to reproduce

Unsure, though this is occurring at high player counts (we've been running at 130 - 400 players)

This is probably a duplicate (I hope not) but figured I'd report since it seems odd. I've been able to relog and have it get fixed.
