Couldn't role on items in new Rabanastre raid - but didn't receive one either

GM told me to fill a bug report on that topic - although i don't think that this is a bug...

Our alliance raid killed the first boss in the new Rabanastre raid and i rolled for an item - but didn't receive it. Then after killing the next boss and wanting to roll again, a message with "you can only roll once per week" or so appeared.
