I will look into that, although it sound more like a game glitch than anything else.
Only real difference between Ion, atmo, and hydro are engines used, that shouldn't impact the projector.

If I try to load it in, the projector stops working and i cant load any other blueprint in anymore.
My only solution was to dismantle the projector and build a new one.
Still same problem.

The "Vector Atmo" and the "Vector Ion" loading in without problem.
