[Dominik][0.17.4] Replacing pipe replaces whole line with fluid of diffrent type

[azureblaze]

Right pipe connected to petroleum, currently empty.
Left pipe full with water.

When the horizontal pipe-to-ground of the petroleum L joint is placed by the vertical pipe-to-ground for water, the whole water line turned into petroleum.

Alchemy, way better than chemistry.

save file attached.

Can reproduce, the full water pipeline becomes full petroleum gas pipeline.

It actually does not change the fluid - water is still there, but it would somehow wrongly assign the fluid to the system as whole and then show it wrong. Will look into it, thanks.

The issue was similar to the linked topic, but in this case I have changed the rules so that it is no longer possible to replace an orthogonal pipe. Thanks for help!
