Was on LFG and joined a fresh start of PoH, did most the work for the party of two I joined. After killing the final boss they kick me from the activity before my pinnacle item drops, went to the postmaster and it's not there. But if I look on the map it says I have done my weekly PoH run and claimed it's pinnacle reward. Is there anything I can do about this or do I just not get a Pinnacle this week?
