I played Halo Wars online for the first time in a year and I noticed that the population count is only " Low Population" instead of a bunch of numbers.
Did 343 or Ensemble do this?
Also, when did it happen and why?
It’s just some weird glitch, sometimes my counter works not often though. It doesn’t affect matchmaking at all at least.
It’s not a glitch. The Halo 3 counter often freezes at 8000 when there are only 1-2k people playing. It’s a lot of work to track that many people LIVE. 
ive been playing alot these last 2 weeks and the population counter is for sure Not working… It has been stuck on “354 players online” all day - everyday every single time i turn on the game. And i know that cant be correct.
regardless, i havent had any trouble finding matches tho, so thats good!
