Will this include the Achievement fix (Endeavor/Evolution) and/or multiplayer on the Xbox One version?

New features look good. I'm also in the crowd waiting for the Xbox One update though.

I have the updated patch...and I played through the game a second time. The trophy Endeavor / Evolution and the platinum still won't unlock.

Thanks for the information! Can't wait for the next update.

I posted a topic on the Tech Support forum too. Seems also be broken on PS4 & PC.
