Hello everyone,
We've identified an issue with the current build that prevents players from accessing the "What If - Gissell" DLC. This problem has been present since the latest update went live on Wednesday.
I sincerely apologize for the inconvenience and for not addressing it sooner. I had to travel unexpectedly due to a family emergency and have been away from my development setup, which prevented me from preparing and publishing a fix.
I'll be back tomorrow, and my plan is to have an update ready and released by tomorrow afternoon.
Thank you for your patience and understanding. I'll post another update as soon as the fix is live.
