I am not sure I would call this a bug. If there is no starting pressure we simply don’t know how much gas we have, so we cannot base any calculation on this. One could argue that the starting pressure should be initialised with the working pressure and I just pushed a commit to that amount but I am not sure that it’s obvious we want this.

The other problem I will look into later today.
