Hi Peevs83,
Thank you for checking those, I'll keep an eye for your update on them.
There is a connection issue with the XB1 version of the game where players are unable to connect. This started a short while after the release of the game. The team issued a fix, and it did fix the issue for 50% of players. It then became apparent there was another issue that was being overshadowed and some players still could not connect.
Because of the amount of varying factors between player setups, it is very hard to pinpoint what is causing the issue. The team have not given up and are still looking into solutions for this. However, from the information I have gathered for them, some common threads seen to have appeared with certain systems. The BT Home Hub 5 router in the UK for example, was one of the common threads. However, we do not expect players would ever need to open ports or change hardware in order to play the game, but until we find what is causing the game to lose connections or not connect all together a lot of the workarounds involve tweeking various factors, like how the internet connection is being made to help players play.
All games have their multiplayer connections set up differently so it can sometimes be the case that multiplayer would play better on some that others when it comes to the players unique setup. I am not saying however, that this is within normal range for 7DTD, we are aware there is an issue here and are working on fixing it.
I hope that helps answer your question, if you have any others I will do my best to answer.
