you are branded so you can not enter the place theres a lot of places like this litterally a case of soft bad end load older save but i will forward the thread to eccma as a possible UX issue maybe add a sneak in option?
Viewing post in Unfair softlock under circumstances in quest Fishkind Research
Of course, you can’t get there because of the slave stigma. This in itself is not a problem, except that you will lose access to Eliza, who in this particular case is inside this location. I had over 5 hours of slave carousel with Dipon and the Fishmen before I realized the problem. I literally didn't know for a very long time that I had mechanically lost an important NPC and the opportunity to get rid of the slave stigma. But the context of what was happening did not give me the slightest hint. That's why I created this post. I don't know how best to fix this. I don't know the game architecture. Just wanted to let you know that without fully understanding the game at this point, you could mess up your save and not even realize it.
It may be difficult for you to understand me. I have to use Google Translate. Sorry.
