I was playing with a streamer on his Don't Starve Together world and it was getting really laggy at some points, causing the streamer to die multiple times. Whenever he looked at the player list I would always be the one with the worst connection so he thought I might have been of the cause for everyone lagging. I've played with him on other worlds before and no one would lag. I would sometimes lag but not as bad as it was on the world he was on today. The world he was on had mods that added shipwrecked items and biomes and stuff, and it was his first time trying the mod out. He fought that it might have been one of the factors of lag. He also fought that my internet was worse today compared to other days but it has been fine for me outside of the server. I have good internet but since I'm in the UK and he is somewhere in America my connection is usually not the best.
Can having bad internet or connection cause the host of a server and everyone else to lag? And if yes then can it cause others to lag to the point them rubberbanding?
