Thanks for setting up test project and providing these details. I was able to reproduce issue in 4.5.1 as well as our internal build, so I have entered a bug report for developers (UE-4873). I will let you know when I see any updates on it. Thanks for report!
This has made Solus very unstable so it is really important that a fix come along for 4.6, because 4.5 is causing other crashes for me I’ve never seen in 4.4 and prior, and related parts of code base are same! I am quite convinced its all related to body welding / attaching of actors!
This is actually unrelated to attachment or welding code. problem here seems to be a PhysX bug with way CCD flag works. For example if you remove your attachment code and replace it with a call to SetActorLocation you’ll get same crash.
I’ve submitted a temporary fix for this while I await NVIDIA’s response to make sure we’re not doing something else wrong. You could avoid this issue by turning CCD off on your simulated object, or you can grab my change from github.

Any update on this matter? Sjoerd is reporting Solus is still getting crashes due to attachments, just wondering if anything new has happened on your end
Hey there, sorry I missed your response. Before you responded, I was still encountering bug in 4.7 preview 4. I’ve just now converted my project to 4.8 preview 4, and bug seems to be fixed!!
I can finally continue working on my game! Woohoo!
