We've posted an update to the MHII 1.28 pre-release. We did a lot of work on the game balance and AI in the wake of the addition of Idle Arms and Oil consumption for units. We also fixed some game and AI bugs that were causing problems with production and supply. We will continue to work on balance but I think you will find this a much improved experience. And we improved the data in the Combat Reports!
