There is a rare chance that `gson.fromJson(Reader, Type)` will return `null` in the PlayerHandler loading process, which causes an NPE to happen.
This should be fixed now and AdvancedServerList will print a warning about the JSON not being parsable, which seems to be the only explanation for this to occur.
