Thanks for all of the feedback we’ve received over the last few days. We’re hard at work addressing as much of it as possible and plan to incorporate more into another patch that will happen later down the line. The main issues we wanted to address were the country selection screen being broken in several mods, as well as an exploit regarding ‘Force Attack’. Both of these issues are fixed now alongside a bunch of other bug fixes and balance changes. Besides letting us know what to focus on, I’d also like to ask if there are any changes people would like to see regarding the patch notes. For example I’ve bounced between using country tags and full names for highlighting purposes. I’d like to know if there’s a preference. **_/Batya_** ##### **PATCH NOTES** ##### **Balance** - Blockade Runner admiral trait requirement reduced from 37 to 32 knots to allow for support and repair ships. - The Grand Assault milestone 'Forward Command Posts' supply reduction was reduced from -0.05 to -0.01 - INS/HOL: Significantly reduced the factories required for the focus 'The Industrialized Colony'. - INS/HOL: Significantly reduced the factories required for the focus 'The Soetardjo Act'. - INS/HOL: The focus 'The Republic of Indonesia' no longer requires a minimum number of civs, mils, and dockyards, and instead only checks your factory count, regardless of which type.
