Ok, that makes sense. I'll give it a try again because I never saw this screen.
Before you go an change anything, I wanted to let you know I am in Linux running "Our Beautiful Land" in Wine. So there is a chance something is not working with Wine. I've run games made in Unreal with Wine in the past and they run fine. I also found that "Our Beautiful Land" wouldn't even Launch until I install Visual C 2010, 2013 & 2015. I wasn't sure which one it needed so I installed them all.
Now it launched fine, but I can't actually play until the client connects to the host and continues. Thanks for your help!
Any chance of a Linux port in the future?
