When we reload the events for a Space, we aren't incrementing the snapshotCounter

Summary: This is apparently why some Spaces are taking a very long time to load: unless we cross the snapshotCounter threshhold (100 changes) in a single load of the Space, the Events keep building up without a Snapshot.

This Space is the conspicuously slow one to load, apparently because it has reached ~1500 Events post-Snapshot.
