I know its a known issue but, the workaround is NOT working for me and many players. Steps 6 and 9 of the Drowning Labyrinth quest aren't able to be completed by some players. Due to this quest being a fix between character-scoped and account-scoped, if you have an alternate character and make progress on the quest, you need to play on that character to get back into the correct research paper level for your main character. Its not a good workaround either expecting players to do the whole set of steps again to hope it then works plus many players dont even have other characters made and many are solos who dont get to constantly run the dungeon - like myself I get to do one time per week and it may only be step 9 but, there is a lot of work involved to get to that point - this is not an acceptable fix! It needs fixing to be account wide and again some who have tried to catch up on other characters are still bugged out. If this was free silver it would be fixed in a hot minute. Please get this sorted urgently for players ideally before Act 2 as its very frustrating and unfair.
