Packet24MobSpawn - HandleSpawn crash (NPE)

Hello!

 

I'm working on a mod that adds a few hundred new mobs.

I'm having this issue that the game crashes when it spawns a mob when I move around the world exploring. it crashes with the following error log:

 

Caused by: java.lang.NullPointerException
2013-08-17 21:14:19 [iNFO] [sTDERR] 	at net.minecraft.client.multiplayer.NetClientHandler.handleMobSpawn(NetClientHandler.java:952)
2013-08-17 21:14:19 [iNFO] [sTDERR] 	at net.minecraft.network.packet.Packet24MobSpawn.processPacket(Packet24MobSpawn.java:143)

 

Following this I investigate the issue and I find that this asignment returns null:

EntityLivingBase entitylivingbase = (EntityLivingBase)EntityList.createEntityByID(par1Packet24MobSpawn.type, this.mc.theWorld);
        

 

Some searching on the net reveals information about the packet only handling ID's less than 255 because it cast them as a byte. I have more than 255 mobs which are added, how could I work around this issue?

 

It may be that there are other ways to do this, if so please point me in the correct path because I'm stumped by this.

If you guys dont get it.. then well ya.. try harder...
