I have a priest at 85. A few months ago I did the quest chain to open the Firelands dailies. Go save Thrall, travel the world etc. I then did dailies on and off for a few weeks and had around 100 marks of the world tree. At the same time I was levelling a Rogue and my priest lay mostly dormant. Probably the last time I did any dailies was about 2 months ago.
I have now joined a guild were my priest is wanted for raiding so today I dust her off and go to do some more Firelands dailies. As I go to portal I spot there is a new quest. I take it (without looking, cos I roll like that) and go into Hyjal. When I get there I realise it is the starting quest for Firelands dailies. Upon inspection the whole thing has been reset. I am back to the stupid long quest chain and have lost not only my 100 marks but also the gear I bought from the first vendor you unlock.
Has anyone else had anything else like this? I have raised a GM ticket but the time is about 13 hours *sigh*
