I have run into a bug that caused me to lose a level of Artifact Knowledge.
Approximately 5 days ago, I used an "Artifact Research Notes" item and reached an Artifact Knowledge Level 17 with 4550% AP multiplier and for all of this week I have gained AP as intended, with Level 17 Artifact Knowledge. I still have all of those AP items in my bank, so I did not imagine it
.
This morning I logged in and noticed that all AP quest rewards were much lower than I've seen in almost week.
When I checked my Artifact Knowledge level – Lo and behold! It read Level 16 with 3600% multiplier. I have reset the cache in case it was a visual bug, but this did not fix the problem.
It seems I have indeed lost an Artifact Knowledge Level
.
I looked online to see if anyone else had this issue and there were a few reports of this in September, but no solutions or known causes. But what I did find was that this bug can allegedly happen multiple times to the same character!!!
Have any of you come across this? Any advice?
