[1.1.69] Mixed fluids from water pump

[zer0t]

What did you do?

1. Decided to play Factorio again and loaded my 1.1.X save that was working fine before
2. Played for a while
3. Closed the game
4. Resumed from last save
5. Noticed my fluid factory was not behaving as expected
6. Tracked down the source of the problem to mixed fluids in pipes
7. Noticed mixed fluids are produced from "lake/ocean" + "offshore pump" + "pump" (see screenshot)

What happened?

1. I have an "offshore pump" from lake/ocean + "pump" connected to a pipe
2. The pipe contains "water" + "Light oil"

What did you expect to happen instead? It might be obvious to you, but do it anyway!

1. I have an "offshore pump" from lake/ocean + "pump" connected to a pipe
2. The pipe contains only "water" and no "light oil"

What did I already try to fix it?

• Empty "pipe" with "trash button" -> "Light oil" disappears -> "Light oil" appears again immediately

So, that fluid it's showing you is not the contents of that pipe, but rather of the system as a whole that pipe is connected to. The problem is somewhere else.

Taking a brief look at your save, I see water in the pipes that are supposed to be light oil input for your chem plants, so I'd say the cross connection is somewhere in there, but your setup is so freaking huge, that I'm not taking the time to debug that.

Dammit, thx for the hint. Didn't pay attention, that it shows content of the whole system.

Time to debug....pls close
