I'm on a Mac, recently got Patch 5 so I played through the last battle to get the epilogue. Initially it's fine, talked to everyone and read the letters so went to talk to Withers to end the game & Astarion's final sign off (he said he wanted to talk after the party?) Problem is Withers' dialogue won't trigger. I'll get "Tav started a conversation" and then nothing happens.

Tried everything I know to do - restarted game/computer but not seeing anyone else with exactly this problem? Not a druid, so can't wildshape and see if that resets the ability to talk with him?

Frustrated because I feel like I'm still missing a bit of story.
