Invisible players/ Need the mega parks back!

We need the parks back.. where is the mega parks from Skate 3. It’s cool to have the open world but we need the mega parks back and be able to have more park options. 
Also when We are playing our friend becomes invisible, or we become invisible to our co-op player. This needs to be fixed other than that. The graphics are good. Just a bug and need more parks. Thanks for creating another we love the skate series!
