You may see this happen occasionally due to a couple factors affecting the display:
- We only show links in the network visualization between the latest values.
- We update user identifiers when they have activity, or when someone they're linked to with a high score has activity.
What this means for the network visualization is sometimes user identifiers will not have bi-directional links.
Let's say both User ID #1 and User ID #2 have recent activity with IP address 22.214.171.124. User ID #1 will see User ID #2 in their network and vice versa.
Then User ID #2 has new activity with IP address 126.96.36.199, but User ID #1 has no new activity. Now when you look at their visualizations, User ID #2 will no longer see User ID #1 in their network; however, User ID #1 will still have User ID #2 in their network (since we haven't updated them yet).
