The online multiplayer menu is actually properly fixed now.
Seemed that while things may work inside of the Unreal Engine editor, they don't work too well on Steam.
I did some very extensive and thorough testing this time around however, and I know this actually works, plus I've tested it on Steam before releasing the update.
I am staying up after another massive day to make this happen, because I don't want anybody missing out on the fun.
Now I can focus on the other bug fixes, in particular, Pipemare and it's dreaded missing pipe segments.
Thank you for sticking with me, I promise I'll smooth everything out as soon as I can..
For now, go grab the update by restarting Steam.
You will know if you got the update, because you should see "ALPHA DEMO" in the top right, and "StinkyFrog" down the bottom right of the screen in the main menu.
