It seems like mirror mode may have been affected by the recent game updates, it used to have the same issues before the 3.0 release, stealth injection should work until we get an update
It does that by default atm, I'll update it to not remove gear between quests shortly
Mirror mode may be broken right now, try stealth injection until we get an update
What's printed in the logger? How does it fail?
Run in debug mode if previously started, it most likely was missing the maze key from the dialogue earlier. Mirror mode has been running fine for the last 2-3 months but now it looks like it's been affected by the recent game updates so won't be able to complete many dialogues on that.
