I am still facing this issue as well. I did not record as some did, the blessings I had unlocked prior to update. I am very sure however that it was more than is being suggested in my masteries. I had many weapons with full or almost full t3/t4, and the most points I got in any mastery was 12. In most I had signifcantly less. Is there a way to understand where I should be in terms of mastery? Im over 1600 hours in and spent a decent chunck of that testing builds in the meat grinder. To test those I had to unlock many many blessings and now Im concerned all of that is lost. Please advise.
