I submitted a bug report in game right after I had completed the story quest “Chapter 9. The Predator’s Path” and not getting the Mastery Point the achievement says I should have received. I still have not heard back from a CSR nor have I received the missing Mastery Point. I also responded to this thread: https://forum-en.gw2archive.eu/forum/support/bugs/Issue-Reports-Heart-of-Thorns-Merged/page/69#post5942867. I quoted another player who had the same issue (his post was from 2 months ago) and there has been no response from ANet since the quoted user had submitted his post.
I know for sure I did not receive one since I did not get the floating Mastery Point Symbol that shows up over your minimap when you receive one. Also, when completing the story quest, I only had 2 Mastery Points so it should have gone to 3.
How long before I hear from a CSR and/or receive the missing Mastery Point?
