@WildOrangutan Could you please have a look at this one? Again, it's a "null brand" error.
While you're there, please check all files so that we can get rid at last of those "null brand" errors.

I thought I checked for all cases 🙈 Sure, I can fix the rest 🙂

This null error, reported by sentry, seems to be the only one left. I don't find any more related bugs.
