Not exactly sure what's going on with this map. We've played on it for a while, then all of the sudden the game starts to desync players. My friend loaded in and as soon as I joined the map, he got desynced out. After he got back in the map ran for about a minute or so then both of us were dropped from a desync. I have attached the desync file. This is 100% vanilla with no mods.

Hi, thanks for the report.
Does you know if any of the players was playing on Mac? If so the desync is solved in 0.15.40
