Oxidizer tank or fuel tank will randomly empty themselves if clicked while set to lower than max amount.
They also expel all their contents if the slider is adjusted below the amount currently stored, instead of just the extra amount.
You also cannot manually enter a number above 999kg in the oxydizer tanks text box and can only select numbers higher on the slider
Steps to Reproduce
build oxydizer or fuel tank, set a cap and fuel it
