Hi Mikiok,

I tried to reproduce this in a new project in 4.6.1, but was unsuccessful. Does this same crash occur if you do same thing in a new project as well as your current project? Was this a Blueprint Actor in level? Can you give us some detailed steps to reproduce it? Please and attach log from your project’s Saved\Logs folder after this crash occurs. Thanks!

Hi Mikiok,

We haven’t heard back from you in a while, so I’m resolving this post for tracking purposes. If you’re still experiencing this crash, please feel free to respond with information requested above and we can continue investigating. Thanks!
