Doing both Eustrin and Warden in 5.3 means you cannot select having Eustrin help for the +5 influence.
Edit: Similarly, during Tyna's quest "Explain to a Concerned Noble in the Library the Source of the Demon Attack to Tyna in the First Part of the Succession Crisis" is unselectable.
Wendis's Request is not granting the +1 to Simon Recovery
Edit: For warden, you also don't have the 'clear the twin's mind' dropbox in section 3.
