Bluehole have updated the test servers and will be reseting leaderboards on January 31

Looks like the New Year holidays have come to an end for all of us and the game developers started working hard on polishing the game. Today they updated the xbox version of the game and uploaded the patch on test server:

Players, as with the last patch, a new type of anti-cheat solution, which is still under development, is to be applied on the test servers. We are in a test phase with this solution, and its stability and compatibility need to be verified. We would like to collect data about potential compatibility issues, analyze it and solve any issues that may emerge.

If you experience a crash, please take a screenshot that shows the error and report it here.[forums.playbattlegrounds.com] If the current test build is consistently crashing for you, we recommend that you play on the live servers instead. Thank you for your understanding.
Please find the patch notes below:

World

• Miramar improvements
  
  • Added more buildings and cover across the map to improve the engagement experience
  • Added more off-road routes for easier vehicle navigation
  • Upgraded the item spawn level of certain areas for loot balancing (some areas will spawn better loot)

Replay

• The replay system has now been updated to a newer version and past replay files cannot be played anymore

Bug fixes

• Fixed the issue where heal and boost items could be used underwater
• Fixed the issue where characters would get stuck in certain areas on Miramar
• Fixed the issue where wall textures on some Miramar buildings were not displaying correctly
• Fixed the issue where certain buildings near by Hacienda del Patron were not displaying correctly

Thank you.
