You're not doing anything wrong, and there's mail support.
It's just the bot decides when it wants to work.
We use a persistent routine when it comes to vendoring/repairing/mailing. 90% of the time this routine works, the other 10% of the time - it doesn't for no reason at all.
I've managed to patch most of these issues, but I've just not got around to the Halls of Lightning mailing issue yet.
OK good to know, this will be quite profitable once mailing is fixed, time to get some battlechests methinks
