Tekkit server issues

[szucs2020]

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

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!

I just forgot the top part of the NEI error:

[WARNING] Failed to handle Packet: java.lang.NullPointerException

You can modify your original post. No need to double post.

I'm not sure about your problem though.

I get that problem, so your not alone :P

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.

[Greytonic]

Both of them, which host do you use?

I'm having the same thing about the NEI mob spawners appear on my home server when I get disconnected as well.

Any luck with the NEI problem? http://forums.technicpack.net/index.php/topic,2696.0.html doesn't help at all...
