I’ve been hosting listen servers, both build and spacebuild, pretty much every day for a few weeks now.
However, I seem to have lost the ability to do so. The only recent change I’ve made to my PC is uninstalling Avast! and putting MSE on. I did that yesterday, and my server was working fine so I think I can rule that out.
The only thing different I’ve noticed is now, when I click Create Multiplayer, and choose a map/gamemode ETC, the loading screen says “Starting Local Game Server” instead of whatever it used to say.
