Crash when destroying two components in a specific order in this user's project

Crash when destroying two components in a specific order in this user's project.

The crash occurs under two circumstances inside the LogActor Blueprint: either DestroyLogPart is called for both TempHalflog and TempLogActor (in that order) and it crashes instantly, or if you only perform DestroyLogPart on the TempHalfLog it crashes on leaving PIE.

Sorry, this user's blueprints are a mess but I couldn't reproduce the issue in a new project.

Reproduced in 4.9.2 binary and Main (CL 270970)

1. Open the attached project
2. PIE with Players set to 2
3. On the Server, approach the fallen log
4. While facing the log, press F to line trace to the log

Result:
After a successful line trace hit, the editor crashes
