Crash when not calling Super::PostInitProperties

Hi,
when overriding PostInitProperties in an Actor the Unreal-Editor crashes after building, when not calling Super::PostInitProperties in the declaration. Afterwards the Project can not be opened anymore without crashing the Editor while loading at around 70%. The actor needs to have an instance in the level (dragged into to world) for that to happen.

What can be done to “rescue” such a Project?
Is there a possibility to prevent crashing when making easy to make errors like forgetting a super-method-call?

Kind Regards

Follow Up:

Crash Message:
Unknown exception - code 00000001 (first/second chance not available)

Fatal error: [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.7\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectGlobals.cpp] [Line: 2008]
MyActor failed to route PostInitProperties
…

So it more or less says what’s wrong. Nevertheless I would like to suggest to make it more user-friendly by either not crashing the editor or giving a hint in the crash report. (Something like: “PostInitProperties requires a Super call. Maybe such a call is missing.”)

It has been long time, so you probably had solved it, but for anothers:

You must completly clean your project - not only clean from Visual Studio, but also you should delete build folders. My .bat file is like this:

rd /s /q .\Intermediate\Build
rd /s /q .\Binaries

That file is located in root of my project - alongside .sln and .uproject files.

Then you must rebuild your solution and voila: now it works.

When you getting crash after some error and you thing you solved it and error still occures, try completely rebuild project. 95% chance of success.
