I put 154 hours into the one save game I had here just for the update to basically say I have to start over. I'm not happy about it but I love the game too much, Just wish I didn't have to start over from the very start. I put so much work into that save too.
Sorry about that, at the end I just made too many changes in the code itself to make the old saves working.
Like someone already said, I tried to make up for it with the cheat option so you can add yourself any kind of item to limit the grinding.
I only hope at the end it will be worthy, as at least in my opinion the game looks better now.
