I was paying around $9.7m per day in total bills. Recently, the black sphere had an event that reduced this to around $9.6m, but the event has now expired. However, I now notice that even my infrastructure bills alone come to nearly $10.1m. That is a rise of $400k, when I have not changed my trades, bought infrastructure or got events that affect infrastructure maintenance cost. I have read of other people in my alliance facing the same issue (of an unexpected rise in infrastructure bills such that they exceed the total bill from before). Why is this happening? Is anyone else experiencing the same?
