Did some fault finding, seems to be only when saving, autosaving or manual

not really, but in the old MP, we were able to stay connected for hours, we havnt changed anything, both our connections have factorio port opened.

When ever my friend and myself play multiplayer, he will randomly get kicked every 4 to 5 mintues, having to reconnect.
