I created a USACO Guide Group recently. On the leaderboard for a specific assignment, it shows which problems someone has solved so far. I’m not sure if this is a bug, but it isn’t showing the problems in the correct order. Like the first three problems of the assignment were P2, P12, and P13 respectively.
If this hasn’t been fixed, you should create an issue at Issues · cpinitiative/usaco-guide · GitHub and include a screenshot.
