Bonus rolls on alts

I know this has been covered in the past and was fixed however just did it now and it worked.

Tried both heroic and mythic

Kill HFC boss in any difficulty - log over on alt - get invite to group - bonus window to roll pops up as soon as you take portal to tannan jungle, don't even need to take port into hfc.

If you're like me and been 13/13M for a while and have heaps of bonus rolls, just use them for alts
