Yes, this happens almost every day so would be nice for it to be fixed.

I sadly don't know how to reproduce this. There are more issues like this: #1054, #1250, #787, #876, #1281 -- but they are all 2-3 years old, so I'm hoping this is not relevant anymore. Please feel free to make a new issue or comment here if it's still a problem.
