Hi everyone,
I was able to reproduce this in 4.6.1 using Blueprints. I tried using the code that had been provided in the original post, but there may be some additional implementation that wasn’t mentioned because I could not get it to do anything for me. Using Blueprints however, I was able to get the same crash that was described in the original post. I ran the same test in our latest internal version of the Engine and the crash did not occur there. I also tried setting up my test in 4.7 Preview 4, but kept running into a different issue that prevented me from being able to fully test the crash mentioned in this post.
I was also able to find an existing report that had been entered about this issue (UE-5421). Its current status is Fixed, and it is pending confirmation from our QA department so it can be closed.
