When you cannot find your run there are usually one of a few explanations:
1. Your Run May Not Be Your Highest Scoring Run
By default, your character profile page shows only your highest scoring runs. However, you can click an individual dungeon from the table to see all of your recorded runs for that dungeon:
2. Your Run May Not Have Ranked High Enough To Be Recorded
Raider.IO makes use of Blizzard's Mythic Keystone leaderboards to collect information on the runs that are completed. However, Blizzard only shows the top 500 runs for each dungeon, so if your run does not rank within the top 500 then there is no way for Raider.IO to record it.
We have reached out to Blizzard to request ways to access more records, but there is no confirmation yet on whether there will be changes made to Blizzard's API.
Our advice here is to try to run your dungeons early in the week, so there is a higher chance you will end up on the Top 500. By the end of a given raid week, the leaderboards tend to be saturated with high level runs, so if you are not competing at that level then your run is likely not to make the board.
Additionally, if you run with cross-server players who are on lower-pop connected-realms, then there is a higher likelihood that your run will be ranked.
3. Our Crawlers May Not Have Scanned Your Run Yet
Our Crawlers are continually scouring for newly completed Mythic Keystone runs. However, this is certainly not an instantaneous process, so if you have just recently completed a run you will need to first wait for Blizzard to show your run on their leaderboard (usually takes about 30 minutes to an hour), and then wait for our crawlers to detect the new run on those leaderboards.
We've provided a way to directly scan a specific realm's Mythic Keystone leaderboard, so if you ever see your run on the Blizzard leaderboard, but not yet on Raider.IO, you can queue it up here: https://raider.io/add
