We're aware of the situation with global, but I'll tag my fellow admins since I'm on the road right now. @Administrator
I have had the same issue yesterday and a month ago. It's been "fixed" a couple of times already. It still happens randomly.
It seems to return every now and then and is random. Possibly making affected testing of fixes impossible. So it'spretty gonna be reoccur unthil one of the fixes works.
