I must admit I'm a little conufsed as I can't reproduce the bug. The quest work fine on my side. The dialog you see belong to another worker. If it doesn't bother you, you can send me your player-log file to ABDLsparrow@protonmail.com so I can analyse it a bit further. Generally speaking, I prefer if you send me a mail for bugs so it's easier for me to tracks theses instead of comments.
As for the other bugs, I'll look into it. Thanks !
