Hello there @Dark_Angel1099! Welcome to the forums
I'm sorry to hear that you've encountered trouble with "Holy Day." Thank you for taking the time to share your report within this thread.
To help us to look into this issue further, would you be able to provide a video that shows this issue with tying up the Thegn occuring in-game? In the video, please can you show that you have the most recent Title Update installed. You can check this in the bottom right-hand corner of the main menu.
I'd recommend uploading this video to a sharing platform, such as YouTube or Google Drive, as this will allow you to post a shareable link within this thread we can take a closer look at.
Thanks!
