Crash on startup loading 4.3 project. Related to canvas?

Hey folks. I have a racing game I’ve been working on for the past month, and it was all going fine today (I updated the project to 4.3) and several hours into the day it crashed. And I cannot open the project now. It loads, and shows the view, then crashes. I was told in IRC that the errors are something to do with drawing to canvas.

Here is my log:

I am running Windows 8.1 x64
NVidia GTX 780 3GB
Intel i7 2600K
32GB DDR3 ram

Please help if you can. we’re in the middle of a crunch on this project!


EDIT: Here’s another log:

Figured it out, and I believe I found a bug.

I am in a blueprint. if I add a child actor, and set it to class “Sphere reflection capture” the editor crashes.

If it doesnt crash then immediately, then it does it on the next load of the editor.
