Adds more pipe connections to allow assembling machines (including chem plants, oil-refineries (toggleable by settings)) to pass through fluids, like electric miners.
all fluids (expect water) are dropped after activating this mod. .. all my tanks are empty now.
think because all existing chemical plants and electrolyser are replaced with new versions at loading
That is not a mod issue.
This comes from the "no fluid mixing" feature from base.
Because of the new fluid boxes, some of your pipework may have a "mixed fluid situation" at which point the game will remove it in order to maintain the no mixing.
