If you have all 12 research notes now do you still get the Research File Cabinet or was that just when they were initially released?

no way to know for sure without asking. I think you are better off filing a Ticket in Help.

I never bought Baenwurath on the date it was available and bought it from a user who had an extra copy to sell because it wasn't possible to buy the Research Notes from the CS.. It worked to get me the Reasearch Notes then.. Now that it is available, I am not so sure.

It worked for me last year when I purchased them all, but someone else in the battle chat forum was having this issue as well the other day. You should file a ticket so they can give you the item, and hopefully they can fix it for future battlers.

Thanks for the info and advice

you are welcome
