Scene graph fps dropping followed by full client crash

Summary

We have made a tycoon game completely with scene graph. As this game progresses and we spawn more entities into the scene fps just continually drops until the game is unplayable.

This extends into the following issue whereby after teleporting away from the main island, the game will crash. Completely crashing Fortnite regardless of platform.

Below are the logs we had:

we find the following particularly concerning
