Which problem are you getting? the badly handled packet or the other one? I can't figure out the badly handled packet one but the other one is because of the server hosting company I use. The way it formats mods is different so I have to ask them how to do it.

Im pretty sure that the normal tin/copper is from industrialcraft whereas the other tin/copper is from redpower mod.

I just forgot the top part of the NEI error: [WARNING] Failed to handle Packet: java.lang.NullPointerException

I have a Tekkit server that I was recently trying to update to 2.0. I updated the map, then I updated all of the config/mod/everything else files and Started it up. Most of my mods started up fine, but then I started getting errors like this one: INFO RegisterEntityTrackerEntry error: entityId cannot be greater than 255. 25.02 18:16:11 [server] INFO > I also get ones like this: (which I think might be conflicts of recipes? idk) INFO java.lang.IllegalArgumentException: Slot 241 is already occupied by codechicken.enderchest.BlockEnderChest@4d8ce14a when adding ic2.common.BlockRubSapling@5c1ae90c How would one go about fixing something like this? The second part of my problem is on my home server, I updated and this one actually works. When I join though, I get null pointer errors like this one: is there something I have to change with NEI? java.lang.NullPointerException java.lang.NullPointerException at net.minecraft.server.mod_NotEnoughItems.getMobSpawnerPacket(mod_NotEnoughItems.java:571) at net.minecraft.server.TileEntityMobSpawner.k(TileEntityMobSpawner.java:114) at net.minecraft.server.EntityPlayer.a(EntityPlayer.java:360) at net.minecraft.server.EntityPlayer.a(EntityPlayer.java:259) at net.minecraft.server.NetServerHandler.a(NetServerHandler.java:324) at net.minecraft.server.Packet10Flying.handle(SourceFile:126) at net.minecraft.server.NetworkManager.b(NetworkManager.java:231) at net.minecraft.server.NetServerHandler.a(NetServerHandler.java:101) at net.minecraft.server.NetworkListenThread.a(NetworkListenThread.java:78) at net.minecraft.server.MinecraftServer.w(MinecraftServer.java:543) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:441) at net.minecraft.server.ThreadServerApplication.run(SourceFile:465) Either way, these errors are probably my fault in something I did, but I would be good to know what I need to do to fix it. Thanks in advance!
