At the start of the map, once I get outside on the minecart, the game crashes.
if you load up the map while holding the "S" key to go backwards just beyond the crash line and turn on far render distance you can actually see a massive wall of "colored snow" or corruption this might be due to some block that got a change in the newer versions and the map hasnt been updated to use the new block so the noise causes a crash and chunk corruption the way you could get rid of it is to just downgrade the "client" version to what he says to use
