The exception seems to suggest I'm doing something wrong in the read/write methods, but they seem to be perfect mirrors of each other like they should be. Can anyone help?

Have you registered all of your messages with unique IDs? This can happen when two messages are registered with the same ID and FML uses the wrong message handler on the receiving side.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

Ah, yes I was making a mistake with my registration - I was doing it on one side only, but it needs to be on both, so the IDs were messed up.

 

But now I have a different crash, because most of my server->client packets call client-only things like Minecraft.getMinecraft(), resulting in NoClassDefFoundErrors. What should I do about that?

You need to handle any references to client-only classes through your proxy, with methods that return the client player, the client world, etc. In your client proxy, implement these to return the appropriate values. In your server proxy, implement these to throw an exception (because they should never be called on the logical or physical server).
