If you get vanquished in a 2 day hardcore world is kind of good because like that you will become better on your next world. Plus 2 days is nothing, 1 Minecraft day is 30 minutes if you don't sleep, and a 2 day Minecraft world is 1 hour if you don't sleep.
i got killed by A GODDAMN ZOMBIE
i couldnt kill it cuz my pc is lagging too much so i closed the game and when i opened it the next day the zombie was still there
