blueprint "modified"

[Chosen Mimes]

so i built a ship on a server....at least i started building a ship.
and it was relatively big so i wasn't able to finish it in one run.

so i stopped after 2 hours, saved a blueprint, set it to private and left the game.

-a few hours later-

i tried to buy the blueprint of my ship so i could continoue building it.
but no! the blueprint is modified! don't know how or why. just some work flushed down the toilet.

The same problem, worked on the damned thing for over a week, had various saves of it just in case, last two version of it were \"modified\" (I don\'t know how) and were deleted from my blueprints folder.
