Hi @a346573450, please take a look at the documentation here: https://docs.colyseus.io/state/schema-callbacks/#onadd-fn-item-key-triggerall-true

You seem to be using 0.14 callbacks (.onAdd = ..., .onChange = ...).
The way to attach callbacks have changed on 0.15 to use callbacks instead (.onAdd(...), .onChange(...))

I hope this helps! Cheers!
