Try a player other than yourself.
clicking on list of games in Explorer for specific user returns wrong list

I tried the steps until I had a problem. The 620 games were listed with appropriate games except for 1 thing. No games from ergodicbreak.. Yet you were one of the search parameters.

hey Ken, that's how I orginally discovered the issue, studying my NSPCL opponent
What team are you on?
There seems to be a bug in the Explorer page. Following these steps:
1) Go to Explorer, https://www.chess.com/explorer
2) Select Other Player and enter a player, ergodicbreak, click Find
3) Click e4 and then e5
4) Looking at the next most popular move (e.g. Nf3) click on the list of games (i.e. the number in the second column, currently 620). It is this link:
https://www.chess.com/games/archive?fen=rnbqkbnr/pppp1ppp/8/4p3/4P3/5N2/PPPP1PPP/RNBQKB1R+b+KQkq&color=white&gameType=recent&username=ergodicbreak
5) Select the first game in the result list, this one https://www.chess.com/live/game/2463906426
6) The opening was actually 1. f4 d5 2. e4
So for some reason the list of games for a given move sequence in the Explorer doesn't have the right link to return those games.
