Attached Project Crashing on Play When Using World Origin Rebasing with World Composition

Questions & Answers
Description

The editor is crashing in the attached project on PIE when World Origin Rebasing is enabled. According to the user, this did not occur in 4.13, but I was unable to test any further back than 4.15, as I was unable to reproduce the issue locally without using the user's supplied project.

This has also been reproduced in 4.17 Dev-Framework CL# 3397002

Steps to Reproduce
  1. Download and open the project: [Link Removed]
  2. Open the WorldBrowser_2017_Test->WorldBrowser_2017_Test->Master_2017 level (this could take a while as it is a very large level)
  3. PIE (No crash occurs)
  4. Navigate to the World Settings and enable World Origin Rebasing
  5. PIE

Result: Editor crashes
