So I'm creating a new dimension, and I already created the portal block and some other things, but when I go to the dimension I get a crash error.
However, when I go back to the world, I'm in the dimension.If I leave and try to re-enter, the same crash error appears.

Here's the error:

---- Minecraft Crash Report ----

It says something about Packet9Respawn in the java error thing, so I'm guessing I have to edit that.(Because I have to edit Packet24MobSpawn for mobs, but I guess I could be wrong about the packet for the dimension.)

However I don't know what to do :/
I know its sort-of a small annoyance because you can just re-join the world, though actually people would get annoyed because it actually happens every time you join the dimension and a good mod has no crash errors -_-
If you're a modder that knows more about dimensions, how do I fix this?

I'm using Pudlehund's Dimension API and Risugami's ModLoader, btw.
