Build failed to load?

[Lady Thanatos]

First off: Thank you, thank you, thank you for all the work you put into your builder, Mids.

The reason I'm posting is that I've hit an interesting snag. Previous to the I12 update, I had worked on and saved a build for my Merc/Traps MM. I just tried to open the saved file and got the following error:

ExtractandLoad Failed

Unable to locate data header - Magic Number not found!

I don't think there were any slots or enhancements in the build as I was only at the state of power layout. Nothing quite like flying by the seat of your pants with leveling.

How did I break it?   

Thanks!

...is 42 the Magic Number?

[Mids]

Hmm, can you email me the saved file? I'll take a look at what it's doing.

And thanks!

(Not quite 42 - The magic number will be either 4D78440C, 4D78447A, or 4D48447A. I like 42 better though.)

Not a problem for me at this point (just deleted and remade the build), but I also had a pre-I12 Mastermind build that failed to load. Mine was Merc/Poison. I got the same error message.
