Teleporters make the worst messes.
At the organic level, you can get organs out of place, vessels bursting.
At the genetic level, you can get mutants and monsters, if the person doesn’t die of cancer or some other disease.
At the molecular level, you can get a wave of organic sludge-water.
At the atomic level, you can get nuclear explosions.
Those are the worst, right?
So, my advice: keep the analysis array aligned, the power conduits monitored, the gaskets and seals firmly in place, and clear the pattern buffers after every transport.
Oh, and use a shuttle when you can.
