The second half of your question is the one worth chasing, and it's a rate versus count problem.

Related games traffic is low intent by construction. Somebody clicking a tile next to another game was not looking for yours, so a large block of those visitors will never follow or collect. If views doubled and follows per view halved, that's arithmetic rather than damage.

So compare absolute numbers, not rates. If follows per day are roughly flat while views went 400 to 800, nothing broke. If absolute follows genuinely fell while views rose, that's a different problem and worth a ticket.

One caveat on that table. It shows only a top slice of referrers and it leaves out visits that arrive with no referrer at all, so the mix can look like it shifted when your other sources never moved.
