The story is very simple. Minutes ago, I played mnt fortress. I managed everything inside the cargo, crafting everything people need.
Suddenly. One strange guy came in, said"I have blueprint" and mined everything.
But the problem is not the arrangement of buildings. The whole team just doesn't mine. Ores are never enough at any moment.
I quit the game, I think all the buildings are gone now, and the new building according to the blueprint has no chance to work.
Because people simply don't mine.

So, if blueprint is banned in that map, this would never happen.

Or you can stop playing with random strangers. Or you can set up permissions on your server so that random strangers don't fuck up your factory.

As Koub said. No blueprints is not a solution.
