Yes, the rest of this event is still work in process. You can not interact with Paulo and John after you cure John.
I'm not sure about zone system so I may misunderstand about zone you mention. But if pier mean a area where Paulo has mention to and basement mean the door that we choose to shut the door tights, yes, it still work in process.
Can you kindly explain about zone system for me? like how to call zone. Because I usually confused when I read update logs.
