Help please. Our computer crashed and the world where my son had built his house vanished. I followed instructions I found on minecraft.gamepedia.com for recovering corrupted saved world data - replacing the following with ones from a new world -
level.dat_mcr (not always present)
This seemed to work but we couldn't find the houses we'd built or the lava pillar we built to mark the spot. We've flown around in all directions for long distances and found nothing. I didn't know about F3 and coordinates before we lost the world so we don't have any for our houses. There are beds in the houses but I'm not sure if we ever slept in them as we couldn't figure out how that worked and we're in creative mode.
Is there any way to get the coordinates for our houses from the saved files for the world? Sorry if this question is not asked well - I'm a bit lost in this stuff but trying to recover it for my young son.
