I won't suffer from the correct hydro costs:
At the moment I have nothing to relay (despite max relaying everything), my miners have gone on strike and are refusing to mine as I have no storage, I can't do blue star yet because there is no storage, and I still have over 3 hours before my dark arts refresh.
However, I do recognise this won't be the case for the majority of the players and think it would be beneficial for the game that people don't feel they are being "denied playing"
I totally understand that Hades Star deliberately has sub optimization built in to force dilemmas (eg: you can't connect everything by a single network of warp lanes to force choices to be made on what you use for drone, or to split the map into islands of networks etc) and that it can be argued that the transport costs are designed to make players choose which arts they sacrifice (IE, you can't bring back everything, you have to choose what to save)
The D11 art tonnage is probably an extreme example of this - we aren't expected to bring more than 4 back, probably that's the point, so choose the 4 wisely - but after a year of players bringing back everything due to a bug, the intended design no longer exists in a vacuum. Suddenly going from a game where players can bring back everything in multiple red stars a day, to one where the arts are suddenly a highly scarce resource, it will be a very negative experience for the players affected by it (and, as I pointed out at the start, it won't affect me, I can stomach the true hydro prices even if I were to suddenly start taking 6 transports instead of 4)
While it is true, this bug should be fixed, what needs to be fixed is: the hydrogen deducted matches what it says you will be charged.
That can include just making the current hydro charges the legal ones, and updating to UI to say that is what it will charge you.
