Latest patches for client and server are online. Pathing efficiency has been increased by over 70% which means creatures react faster and it taxes the server exponentially less.
Client FPS in areas with super-dense trees has also bee more than doubled. Your mileage may vary, but anyone having FPS issues around the woods before, you should be shitting your pants now.
Stimpaks now require animal meat as their biological component. All creatures have meat of quality reflected by their difficulty to hunt, so the biggest, nastiest things you can hunt give the best meat/hide/bone which in turn make the best healing stimpaks.
