Corrupted save: Unknown entity

[saltyspecula]

I was playing my saves just fine before work and when I came back to load up my freeplay map save, I got this:

Notice:
Unknown entity basic-transport-belt-to-ground (Maybe you loaded alpha save from demo)

Attempt to use different prototype to traverse save of already removed entity called "basic-transport-belt-to-ground" failed. There is no other prototype of the same type (transport-belt-to-ground) to be used to load the entity.



I don't suppose there's anyway to recover my save is there? I don't want to have to throw away 12 hours of work. <_<
