I have the same issue,
I'm entering the lighthouse and have a blackscreen... and then I am standing in the hallway, still with the quest intact telling me to talk to the companions, but no hint on how to do so... i already went back several save-files, but no matter what I do, after i come back from "Something wrong", I am stuck. In some savegame files i am even blocked from doing other quests once I tried entering the Lighthouse, as there is a red notification in the quest log saying basically saying i can't do anything else before ive finished "A Change on the Wind" - which apparently i can't. Pls help, i dont wann start anew😭
