Pure virtual function call crash

Unfortunately this still occurs, it only happens in blueprint, and is completely random. It is usually when I am pulling off a node and about to plug it in to another. Doesn’t matter which node.

This is leading me to believe that maybe this is a Windows issue? The engine crashes right after I click OK on the crash prompt.

Would it help if I included the crash report info for the next time it happens? I’ve submitted it dozens of times since this started happening.
