Hello @MaxGoerlich thank you for reporting this and sorry to hear about this drastic turn of events!
Can you remember the name of the quest, or the name of the quest giver you speak to who gives you these options, so we can investigate this quest further?
In addition to this, if you have a screenshot or a save file you can send us in this forum, that would also be of great use to us, to help us locate this questline, thank you.
