I actually think it’s a bug.
It happens when you have two links which starts with the same substring.
EDIT: here’s what we have in the JSON
link_counts: [
{
url: "https://meta.discourse.org/t/cant-install-docker-on-linode-aufs-tools-not-found/18416",
clicks: 3
},
{
url: "https://meta.discourse.org/t/cant-install-docker-on-linode-aufs-tools-not-found/18416/99999999",
clicks: 0
}
]
