Last night I talked to Meistr Siva and released her from the gallows which the guards attacked and called for help. However the main guard casted Evasion on herself and it lasted the entire fight. (100% chance to miss melee, aoe) I looked up the evasion spell and if the site is true then it's only supposed to last 1 turn. However she had it on the entire fight. (this was on tactician difficulty). This really made the encounter very difficult. I highly doubt it's working as intended.
