A PC hotfix is scheduled to go out this afternoon (~4:30PM PDT) with fixes for the Escalation game update. This is client-only and will include a small download, but won't require server downtime or impact gameplay.
Patch Notes:- Send Message now functions as intended and no longer brings up the Notifications window.
- Sanctuary now has the proper art on the World Map screen.
- Fixed broken text strings for the LA7 Buzzard.
- Fixed two new crashes occurring on Live.
We are working toward another hotfix tomorrow (Friday, March 13) which may require server bounces and a brief downtime, and will update this thread once confirmed.
