Servers will be coming offline tomorrow at 3AM Pacific (5/27) for approximately 2 hours

Patch Notes:

• Full server and world wipe (we prefer to give more notice but this came in hot)
• Reduced the ratio of bears and wolf spawns
• Reduced the ratio of predator and prey spawns
• Added a delay for damage on zombie attacks to match animation
• Improved the zombie screamer grenade to attract zombies more effectively
• Walkers and runners now have varied attack speeds
• Walkers attack slower and do more damage per hit
• Runners attack faster and do less damager per hit
• Combat knife headshots should work again
• Set Comfort to start at 100%
• Forced scope is temporarily disabled while we made adjustments
• Containers inside a secure structure do not show up for someone if they no clip into the base. They will reappear once the door is opened.
• New characters and /respawn will now place you relatively near a POI
