Requires changing LivingEntity_creativeFlyMixin#canChangeDimensions target, as canChangeDimensions() is no longer overridden in LivingEntity.class. I have changed it to target canUsePortal() instead which has a different purpose to canChangeDimensions(), so please let me know if this is not a good fix.
