If I use FieldSerializer, everything works. But if I switch to SavableSerializer I always get this. No matter how I implement the Savable on given class. It doesn’t matter what I put there. And actually it is read just fine. But shortly after I get this:
java.nio.BufferUnderflowException
at java.nio.Buffer.nextGetIndex(Buffer.java:500)

I was hoping I could get a bit smaller buffer with this. I’m trying to transfer initial game data to the client. And it is a bit big. But almost fits 
And the next step would be something drastic I’m sure…
