the __1__ in

msg-station-index-changed=A station has been added/removed from the line, changing __1__, please check the rules

is replaced with

lbl-jump-to-header=Station #

in the code

I was getting a locale entry not found error when opening the rules list: In 0.15.xx , the liquid_count in lbl-liquid_count has been replaced with fluid_count for the rule wait-condition type... so the locale needs updating
