Hi there, Thanks for your report. This is listed on our [url=https://help.bungie.net/hc/en-us/articles/27062192032404-Destiny-2-Year-7-Known-Issues-and-Vital-Information]Known Issues[/url] page, where a potential workaround is also mentioned: [quote]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.[/quote] The team is aware of the issue and already looking into it, but please give the above workaround a shot and let us know if the situation persists.
