Need help with persistence file.

[SelectHalfling0]

I have been trying to change my kerbal's roles (this is an old save, and my "original" recruited kerbals are all scientists). I go into the persistence file, change their names a few letters, by adding an extra s or taking away an extra t, and it seems to change their roles accordingly to engineer or pilot. When I leave the astronaut complex or try going to their ship though, the Kraken attacks, and freezes the game. When I re-load the game their ship is gone, and they and their crew mates are dead. Does anyone know how to fix this?

I am on a lightly modded install (KAC, VOID, Atmospheric Trajectories, and a few other UI mods) of KSP .90

I you have the time (which would be greatly appreciated) this is the persistence file (unedited): https://www.dropbox.com/s/8g6320rdc0u5j31/persistent.sfs?dl=0
