But that means if someone removes the tank it removes the gas event and
if all they wanted was to change the tank data (as you speculated
earlier) the gas change is gone.
This seems to be more predictable. If you try to remove a tank that is
in use it stops you from doing so. Then you can remove the gas change
event and then remove the tank (if that's what you wanted)

Details, details. I'll fix that.
