Hi, new member here My tekkit region data is corrupt and I kinda want to keep it, is there anyway to recover it or go back to a non corrupt previous save or something? The way I figured out it was the region files is I created a dummy world then copy a pasted files from my old world to this dummy world and narrowed it down to the region files this way. Basically, as soon as I try to start my good tekkit world, my tekkit freezes up and lags like crazy. I suspect its corrupt just from a similar experience that I had with standard minecraft.
