We are playing with 3 Ppl via LAN on the same server. If we are apart from each other at least 2 can play together and fine, the third shouldnt be anywhere near the others. Or all of them share MASSIVE lag. Like unplayable lag. Even worse when joining the same spot together. It takes up to 10min to get it sorted out by slowly joining one after the other and leaving the area. Its unbearable.
If only 2 are in the same spot it works mostly fine.
