Unreal Engine Issues and Bug Tracker (UE-11454)

Description

Running a server from the editor will crash this project. Reproduced by using

UE4Editor <projectname> -server -log

to run the editor.

This does not occur with a new project in 4.7.2 or in Main. This was tested on the project located in my contractor folder, but first reported in the linked AnswerHub post in the user's project.

Only reproduced in 4.8.1 release. Not reproduced in 4.7.2 binary or Main (//depot/UE4/Promotable-CL-2471062)

Steps to Reproduce

1. Download the project aBPMPTD_n 4.7.rar from \\epicgames.net\root\Contractors\Ben.Halliday
2. Create a shortcut for the editor binary
3. Change the Target of the shortcut to "C:\Program Files\Unreal Engine\4.7\Engine\Binaries\Win64\UE4Editor.exe" "[ProjectLocation]\aBPMPTD_n.uproject" -server -log
4. Open the shortcut

Result:
Crash
