Act 4 Mercenary Conversation Bug

When talking with Tavakai in act 4 (I've currently cleared the fog and prison regions) and pressing the "Tekaru" dialogue option as Mercenary the Mercenary repeats a line twice,

"Well, least you lot are free of worrying if he's still there, I guess"
"Well, least you lot are free of worrying if he's still there, I guess"

before proceeding with the rest of Tavakai's dialogue.
