Issue

trying to import the ground zero save file gives the error

[E] Failed to load custom map file '/game data path/Mindustry/maps/groundZero.msav'!
[E] java.lang.NullPointerException: Cannot invoke "mindustry.io.SaveVersion.region(String, java.io.DataInput, arc.util.io.CounterInputStream, mindustry.io.SaveFileReader$IORunner)" because "ver" is null

ver becomes null in SaveIO.getSaveWriter(int version), the version is 8, but versions.get returns null, and the underlying code is rather confusing

Steps to reproduce

You're trying to load a map for a newer version of the game.
