@ubikoreanbbq  I was just finishing the raid of the castle and was able to spoiler in A Sword-Shower in Ancaster. After the mission I was told to go up and talk to Hunwald and before I was in the talking cut seen with him I had no such thing as the blank quest it only appeared as soon as the cutscene ended and the mission A Sword-Shower in Ancaster finished in the completed quest section did it pop up underneath it. After this I got an active mission to go and report to Randvi and I was able to complete and all with no issues but the blank quest box still remains after the quest A Sword-Shower in Ancaster finished.

I have recently finished the mission "A Shord-Shower in Anecastre" and after finishing the mission I am given a new mission to report to Randvi. This issue shows itself when checking my completed quests all I can see is a blank quest box beneath the completed quest I just did and the empty box has no words besides the phrase "completed". I have also tried reloading an older save a bit before the mission gets completed I have tried teleporting somewhere else and going back but nothing seems to be working and the empty quest box remains. If you have a workaround let me know
