I am a little surprised that you think only now about getting permission from bond1 for the zombie animations. Seeing you using those in a commercial (=to be sold) game, I assumed you allready had a kind of business agreement with bond1.
So under these circumstances you where probably lucky, that some mysterious disaster prevented you from selling your game.
Since I know a little about how "fate" works, there are 2 possible outcomes:
1. You'll get bond1's permission and miracously recover 100% of your WW2 Zombie files.
2. You'll not get his permission and recover everything except for exactly the stuff you'll not be allowed to use commercially.
So in the end everything will fit perfectly together. Really cool how "fate" works.
