n2n1's mod Classic Style Hardcore has the mine as a separate prefab and it's fab, but you'd need to check it for any block changes, as he often uses custom blocks. (the file is called exv_mine_hole)
Yeah so far ive managed to get it loaded up, Started upgrading all blocks to their fullest before I start adding more detail & differnt loot... I ignored the idea of just spawning the original as I figured it would be a mess if spawned in but it worked ok so just edditing that at the mo... I searched around for the prefab in question & couldnt find it so thanks, Ill go have a look & yeah ive had his load before & been totally messed up, Last one had 75000 errors lol
