Stats are not affected by Playing

Reproduce:

Create a Realm, break blocks, kill monsters, etc. Then check your stats.

Expected:

The actions performed on the Realm are included in the stats.

Observed:

The actions performed on the Realm are not included in the stats.

Just noticed:

The stats are not being updated for me at all – regardless of what world I play on. Numbers are displayed, but they do not correspond to the truth/are not updated.
