I don't know if this really does anything. but try verifying your files. I verified mine once told me I was missing one then verified again then said all files where there.
oh what the ****. i just verified the game files 2 times before opening the game and bam, i got him again with the splash screen and all every level and item still intact. what the **** ubi?
Yeah the file verification seemed to work for me too, though on the second time, not the first. Ubi, would be useful if you could communicate this as a potential fix for steam users. Still very disappointed by the lack of communication and transparency the past few days.
After reading your posts I verified files twice (because I don't have time right now to test launching game idk how many times without/with verificating), launched game and yes, gryphon is unlocked. Still tho no compensation or any info by team.
