I created a Liquid Reservoir and it has liquid in it. When you build a pipe from it to a liquid vent; as soon as the liquid vent is finished constructing the game crashes.
I did some more testing and it seems to crash whenever I connect anything to one of the liquid reservoir input or output . soon as pipe is finished bamn desktop.
Build a resevoir. Build something like a ethenol distiller next to it. Connect pipe to both.
