Talking heads:
Hi, Simon is here, so I have been trying out the latest version of the game (update 25.2), after completing the trials, have been talking to few NPCs, and when talking to general/common NPCs, it shows dialogue I had previously with someone who is an essential NPC, and it happens that it gets stuck, cannot exit the dialogue with the common NPC because there is no option like "ending conversation" or "exit" etc.
There should be some general dialogue option to be able to end a dialogue whenever you want to.
(I will try to duplicate the error later so could have some screenshots of specific NPCs as proof)
