Hey everyone. So I just started playing KSP pretty recently now and I am having a great time with it. Quite excellent and entertaining (thank you developers!). Anyway, I've started working on some more complex designs using fuel lines and came across something kind of interesting (to me anyway). So I have a situation like this: My naive first thought was that it would drain the single tank on top, then the two tanks connected with fuel lines simultaneously, then down to the rest of the main body. What I assume actually happens is the game looks up the chain of tanks and lines and marks the final tank it can reach as active, then follows any alternate fuel paths as far as they will go marking the last tanks in those paths active as well. In my case however since the very top tank was marked active first, the single remaining alternate path stops a tank below it, since the next one in line is already marked as active, and activates the one it stopped on. So for one thing, I might suggest that if a chain of fuel tanks and lines ends with a tank that is already marked as active then it should simply do nothing instead of activating the next tank down. That suggestion of course is based on quite a few assumptions about how the game is coded on my part and there could be negative consequences on game mechanics that change could have that I am not considering, so feel free to ignore it if I am off on any of those points. My main question though is, are there any suggestions on getting something like this to drain the way I would like it to as the game currently works?
