[Bug] NullPointerException if the config class of mod updated #110
Description
If I update the config class of the mod which is depends on midnightlib, then it will cause java.lang.NullPointerException.
For example, the old config class:
public class MyConfig extends MidnightConfig {
public enum OldConfig {
ONE, TWO, THREE
}
@Entry
public static OldConfig oldConfig = OldConfig.ONE;
}Then I update the class in a new version of mod:
public class MyConfig extends MidnightConfig {
public enum NewConfig {
A, B, C
}
@Entry
public static NewConfig newConfig = NewConfig.A;
}As a result, the mod cannot read the old json file correctly so that it will cause java.lang.NullPointerException.
