Just don't sleep at all anymore, that should add a couple of hours to your day 😝

The latter might be the best, calculating individual aura cost, and having a "personal" converter. But yes, that does sound like a lot of coding work. Out of curiosity, can LLM help you with those things?

Interestingly, my calculations on how much wagons should cost is very close to what your converter shows - and I did calculate with the cost, reducing only the 10% for producing the resources oneself.
