In custom games, choosing Hawkins Lab does not force the map to load, and instead a different map is chosen. (i got first a farm map, then a yamaoka map)
also this is so cool omg
User has already marked this as fixed. Closing report.
Do you know that you can just select the map in the custom game setup?
You don´t need the offering.
I just played it against pretty well playing bots :-)
Edit: Paulie Esther had the same in his video - maybe because it was so new?
