This is an issue that has persisted through me moving to a new address and setting up with an entirely new ISP. I haven't played for several months because of it and just decided to try again since I'm on a new connection.
When I play 1v1 games I can play through the entire game with no lag or any issues whatsoever. This is true over dozens of games. However when I join a game with many people within the first 30 minutes I will lose connection to one of the players and will have to leave the game. This issue is consistent over pretty much every game I have played with more than 4 total players.
I'll post the game.log from that game. I'm looking in the logs folder and only see 4 files; only two of which are dated for today.
I've only just made an account here to ask about this issue. If you need any more information from me let me know.
