I accidentally loaded a save game without Biomes a plenty loaded in my Feed the Beast launcher (I forced an update. For somereason that disabled that mod!)
I crashed to the ground and died as my Fir Tree tree house no longer existed.
I've re-enabled the mod, but my save seems to be borked. I have most of my items (except a handful of fir logs/planks)
Can I recover the game by forcing the game to put the biomes back and regenerate those chunks? If not, how do I carry my items over to a new save? I imagine I can destroy everything and put it into my inventory and then save a copy of my player.dat and regenerate the world, then drop it into the right folder. If I do this, what stuff won't be stored in player.dat?
Is any of this possible? If it helps I'm on Ubuntu 12.
