Playing with a coop partner, he controlled his own character and Lohse, while I controlled my character and the Red Prince.
On entering the room with Trompdroy's soul jar, we freed him and began working our way through the jars, absorbing or releasing the jars as we saw fit. My friend entered the "conversation" with the jar to the right of the door on the opposite end of the room from Trompdroy's jar with Lohse. While that conversation was in progress, he switched characters to his main Wayfarer character (custom), and interacted with another soul jar. When we all finished our conversations, Lohse was locked in the "conversation" with the soul jar, even though she had freed the soul trapped inside and the jar was no longer interactable.
Lohse is now permanently locked in conversation, cannot be used, and cannot leave the conversation. We teleported her bit by bit to the dungeon entrance and brought her out, but that didn't break the conversation. We tried to kill her, but she's invulnerable because she's in a conversation. We tried to quicksave and load, but she's still stuck.
