If you downloaded the mod before 15:00 GMT today (13/01) then you need the following update:
- Download the following file: http://opendayz.net/downloads/DayZ2017/Addons.rar
- Copy it to @DayZ2017/Addons
- Right Click Addons.rar and 'Extract to here'
- It will ask you to overwrite two files (dayz_code.pbo and dayz_anim.pbo.shinkicker.bisign) - Say Yes.
