Fuel drops out of fuel tanks every once in a while

added savegame and proper reproduction steps.

i think the issue is that under certain conditions the slider of the rocket tanks gets reset (even though the value doesnt change). This leads to the current tank content to be completely emptied. It should only drop the difference between the current and the maximum content imho.

I'm having this same issue on my first petro/oxy rocket.  It's been filled and dropped at least twice so far that I can confirm (first by seeing 2700kg of oxylite dead center on the floor under the rocket and second by watching it seconds after deconstructing the gantry to prevent over-filling as the dupes had already put more than the slider was set at).

Confirmed it was the clicking on the oxylite tank to check the contents that caused the dropping.  Slider was set to 900 but watched a full 2700kg get loaded before clicking on it.

Happens to me as well, with petroleum and steam as well.  With steam I think it sometimes coincided with me changing the cargo limit.  I would be adjusting it upwards and all the steam would dump out.

We've fixed this in development and it'll be release in the upcoming Upgrade. Thanks!

@Ipsquiggle: Oxygen tanks seem to be fixed, but this is still happening to the petroleum tank.

I see! We'll look into why that one's still misbehaving. Thanks!
