Weird lack of inheritance problem (or something along those lines...)

[coolAlias]

Try this:

// our entity class:
public class EntityExperiment extends EntitySquid {
public EntityExperiment(World world) {
super(world);
}
}
// no other methods, just plain old inheritance at work here
// entity is registered normally
// no render class is registered, as it uses RenderSquid automatically

When spawning this sub-class of EntitySquid, it renders normally and has the regular tentacle behavior, but for some reason, and unlike the vanilla squids, it never changes its head direction, so the head is always pointing straight up making it look like a weird fishing bobber suddenly moving in various directions.

 

Does anyone have any idea why this entity would fail to exhibit all of the regular squid's behavior? I've looked through all the parent classes for any references to 'squid' to no avail, nor did I find any in the various render classes.
