I had this problem for a while as well. Delete the map if it already exists and then download the maps and put it in /tf/maps. Should fix it.

thanks

Tried it. Didn't work still freezes. I even tried running it locally, starting it on my own machine/privately. Still freezes on loading. No other problems ever with tf2 on any other map... really weird.

try disabling ur antivirus while running it or before starting tf2 maybe try reinstalling again

try removing it from /tf/maps again

I should've been more clear: downloading the map set from tf2center is what fixed it.

It doesn't work for me either.

For awhile I just thought that people joined in before me, but it's been happening every single time the server switches to Viaduct, I just deleted the map but is there any other fix?
