# What is actually happening?

the leaderboard just updated with score `2.0` (i'm the 68th one), and same problem happened to my friend (the 56th one).
The problem why there existed two same user id was related to [Same team name](https://biendata.com/forum/view_post_category/99) issue.

I thought it was related to the [I changed my team name,but both the new name and old name are on leaderboard？](https://biendata.com/forum/view_post_category/101) issue.

This bug was fatal for user who changed their name, and I thounght it should be fixed immediately.
