If there is at least one advanced pressure pipe from PneumaticCraft as part of the ship, ship assembles correctly but when you try to mount it, most of the ship's blocks disappear forever, and the ship stays unassembled. Some other items from PneumaticCraft work fine, i.e. ship assembled and mounted with Flux Compressor and no pipes.
It was the air ship if that matters, with some balloons and some steam engines. Config was changed to require only 1% of balloons (0.01) to count as airship.
I did test only with advanced pressure pipes, not sure about regular ones, probably the same.
