Would be better if you redid the title, seeing the issue occurs at night.

Speaking of crashes at night, there are other issues with this, so there isn't really a need for this duplicate issue.

On the bright side, you at least confirmed the existence (like some others) of this critical bug.

Closing duplicate of #521.
