Compile Blueprint Crashes editor; (Virtual functions table is invalid)
I am using Unreal Engine 4.17.1 (both the GitHub source and the launcher versions). I am running into an issue that has me stumped. In the project that I am working on there is an actor class that we use as a parent to many other classes. This file has been in our project awhile and has had no issues. Recently we tried to change and compile it but this ends up crashing the editor. When we looked deeper into the issue, it looks like the event is triggered by a conditional statement in the UE4 source code. The statement is as follows:
Does anyone know what could cause this, and how we could fix it?
I found a post, that solved my issue with a work around. [Thank you, Burnz]
you have set [/Script/UnrealEd.BlueprintEditorProjectSettings] bUseCompilationManager=False

If any one figures out the original issue, causing this to happen, or if there is another fix, please let me know.
