We're running an internal migration of all old players' stats to our new highly advanced statistics tracking backend. This means that stat changes will be a bit delayed while we ingest this huge backlog of data. Nothing is being lost, it'll just take a bit longer to show up in the in-game UIs.
I've been playing music for about 9 years I think, I started out on the keyboard and started learning guitar ~2 years later. My favourite Pokémon is Snorlax, I wish I could just eat and sleep all day haha
