java.lang.NullPointerException at mapwriter.util.Utils.getWorldName(Utils.java:159) with Replay Mod

Hi I'm using Minecraft 1.8 with the following mods

• forge-1.8-11.14.4.1577
• LiteLoader 1.8 with Forge 1.8
• Replay Mod v1.8-2.0.0

When watching my replayfiles (basically a recording of what happend) I get the following

java.lang.NullPointerException

A valid fix seems to verify if the serverIp is not null:
``net.minecraft.client.multiplayer.ServerData serverData = Minecraft.getMinecraft().getCurrentServerData();
if(serverData != null){
	worldName = serverData.serverIP;
	// ....
} else {
	worldName = "default";
}``
