So I played with 2 friends today, and I hosted my map. For some reason, I was lagging an extreme amount. It doesn't make any sense as I am the one hosting, there shouldn't be any latency.
It WAS kinda funny though. I was sailing around with them, when suddenly the boat faceplants into a wave and gets stuck like 5 meters under water for a good minute before the boat suddenly teleports away. Turns out I and friend #1 were lagging like crazy and dropped out of the boat while friend #2 stayed in the boat and came sailing back.
Absolute chaos. I can't even begin to theorize how any of this happens. Would sail with friends and almost lose everything again!
