Grunt default task only runs first task in the list - gruntjs

Question

I'm just getting started with grunt and just trying to get a few basic tasks working.
Here's my Gruntfile:
module.exports = function(grunt) {
grunt.initConfig({
compass: {
dist: {
options: {
config: 'config.rb',
watch: true
}
}
},
livecopy: {
your_target: {
options: {
source: "C:/Websites/xxx/styles/screen.css",
target: "W:/Websites/xxx/styles/screen.css"
},
},
},
watch: {
assets: {
files: ['**//*.css', '**/*.js'],
options: {
livereload: true,
},
},
},
});
grunt.loadNpmTasks('grunt-contrib-compass');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-livecopy');
grunt.task.registerTask('default', ['compass','livecopy','watch']);
};
I can run each of these tasks individually without any issues. When I run the grunt default task, only the first task in the default task list runs. It doesn't matter which order they are in, only the first one runs.
What am I missing?

When you run Compass with the watch option it runs compass watch which is a blocking task. From the grunt-contrib-compass docs:
watch
Type: Boolean
Runs compass watch instead of compass compile. This will use Compass'
native watch command to listen for changes to Sass files and recompile
your CSS on changes. While much faster than running compass compile
each time you want to compile your Sass, Compass becomes a blocking
task. This means that if you would like to use it in conjunction with
another blocking task, such as watch, you will need to use it in
conjunction with a paralleling task such as grunt-concurrent.
