close the host tutorial would actually be interesting for me cuz my hosts use to stay shown ag after started game. they always did, no idea why.
This is because you use a snooper. By the way, no matter what one exactly -- every currently existing W:A snooper behaves the same.
The subject "tutorial" with language mistakes won't actually close the host, i. e. make it disappear from the list (even when hosting directly using W:A), it will only limit the maximum number of people able to join. E. g. if you've limited it to four, the fourth person that tries to join, will get the "no more room in the game" message window.
A solution for this problem is going to be introduced in TWS 3.0. Stay tuned.
