When I started the new lightfall season I had 9 prime engrams at Master Rahool. I also had some exotic and prime engrams in the Postmaster. I decrypted the Prime Engrams at Master Rahool successfully. Then went to the Postmaster to collect the ramaining Engrams. The exotic engrams were collected and decrypted successfully. I then collect the remaining Prime engrams from the Postmaster but when I tried to decrypt them at Master Rahool they will not be shown. When I look at the tower director Master Rahool is flashing . At the tower he just keeps notifying (flashing icon) that he has something for me and when I look there is nothing shown. The Prime and Exotic engrams where prior season engrams... Game restart and revisit to Master Rahool does not solve the problem.
