Hamachi Version is from the official site. Been using it for years! But if you mean I am using a pirated game, I can send you my Steam profile so you can view my profile for the game is that appease you, Can even invite me there and we can have a talk before making major assumptions.
It provides much better connectivity than using Steam multiplayer feature. Friends joining over steam had ping over 90.This becomes even worse when my american friends join through steam and experience 450+ping, But through hamachi my friends have 30-50 ping and my american friends with 280ping through hamachi. So big improvement and reason to use hamachi to play games that support lan.
We discovered your mod through Neebs Gaming, And we have never in our lives used mods for 7days to die. We played atleast 6 hours of your mod and we had some rough times cause its quite different from base game. First two days we started starving and heck the oranges and tomatoes can cause food poisoning killed two of us, its quite nice to replay the game with whole different set of rules now.
I had no means to offend you and your mod but all this started since We installed your mod.
It could be coincidence, they may be working on the lines between South africa and overseas.
