Gas pumping stopped

I too had a water filtration machine not be able to recognize the liquid pipe supply feeding it after I reloaded a save. Once I deconstructed the water filtration and rebuilt it it began to work properly.

I have a very similar problem.

Basically air pumps don't pump gases except one kind of it. http://imgur.com/a/mucSN

Notice how much of most gases except H2 on the first pic and O2 on the second are stored.

I had this trouble for a long time in my colony and so far I think the problem is that it refuses to pump the gas except the first type it found the moment you build it. Restarting the game seems to reset the process so the first time it pumps something is when it decides what it'll do.

Had the same thing right now. A pump in hydrogen and oxygen, only 1 gas goes out, the rest is stored indefinitely, and when you reload the game it will reset the thing.

This was fixed.
 

Yap fixed now. Thank you.
