Without server bandwidth settings, All Satisfactory servers are reverting back to “Medium” when some saves require higher network quality settings for player to join without timing out.
I have had to apply the Network Quality setting in the server management screen in game and then save the server/world and return to AMP and shutdown and restart the game server instance.
That is the only way I can find to change the server’s network quality setting and get it to stick.
But if there ever becomes better support and server settings I would love to see that as well.
