Footfall not registering. Bug?

I’ve had my settlement for a week and it has stopped collecting coins after just a couple days. I get traffic to the settlement but it’s been stuck at 180 coins for several days now. What am I doing wrong?

Maybe someone else is collecting your coins?
I have no idea how the football algorithm works.

I had that problem not long ago. It stopped collecting coins after I split my settlement into two beacons. It started registering again when they merged with two beacons of two other players forming a larger settlement.
