1v1 ladder games pops up in Play tab for a split second.
I was watching what games was hosted, and I saw a game pop up and disappear almost immediately
named "PlayerX" vs "PlayerY". The game was hosted on Ranaoke abyss. I quickly suspected it was a ladder game. And indeed it was checked the replay 1v1 ladder rating of players.

TL;DR
Ladder matches shows up on hosted games tab for split second.

I guess you can filter them out of popping up somehow? Maybe from the featured mod in the data?

Not a huge issue but hey I report what I find lol
