This is a common crash occurring in the 4.16 release. It has occurred for many users, but nearly every user's project is named some variation of "pinball", this makes me wonder if the repro is surfaced in Chris Murphy's pinball tutorial on Udemy.

repro steps currently unknown. Seems related to "Set Static Mesh" in a blueprint with a Spline component.
