We recently posted a survey as a way to check the community pulse, and it has given us interesting data.

Quite a few people also talked about the potential of getting achievements when playing multiplayer. We’ve not decided on a specific course yet, but we are leaning towards a more bespoke achievement unlock requirements. Meaning that some will require ironman, and others don’t. For now, this is intended to be the last update to the open beta before it goes live closer to our actual anniversary, on June 6th.

Here is another Open Beta Update for our upcoming Anniversary Patch, including some bugfixes, balancing and more naval AI improvements.

We recently posted a survey as a way to check the community pulse, and it has given us interesting data. When looking at the data and the responses on social media, the majority of you believe that ironman should not be required for getting achievements, however playing with mods should suppress getting achievements. We also hear the outcry for allowing specific mods and achievements, but this is unfortunately unfeasible for us. Quite a few people also talked about the potential of getting achievements when playing multiplayer. We’ve not decided on a specific course yet, but we are leaning towards a more bespoke achievement unlock requirements. Meaning that some will require ironman, and others don’t.

Open Beta Update VI Notes
Balance
  • Nationalist China: Reduced focus time from 70 days to 35 days for 22 focuses across the Industry, Army, Air, Navy and Politics branches
  • Nationalist China: Construct the Banqiao Dam moved earlier in the tree; The National Sun Yat-sen University takes its previous prerequisites
  • Submarines now escape at 35% progress per day if they are hidden (previously 50%)
Gameplay
  • Lendlease has better UI logic and will default to maximum amounts that the receiver can handle with their convoys
  • An event will now be fired to all the signatories of the Nine-powers treaty when China gets attacked
  • Ignore convoy limit when sending convoys as a lend lease
AI
  • Updated USA naval templates and strategy
  • Updated generic & UK's ship templates
  • AI now reserves more dockyards for repair (thank you forum feedback)
  • The AI will now repair until critical damage has been repaired (thank you forum feedback)
  • UK builds up north africa port more if its needed to push to Tobruk
Bugfix
  • Crash that can occur when a SAM mission is set to a naval region
  • Crash that can occur on Mac in peace conferences
  • Fixed bug where emergency convoy demand would scale infinitely
  • Force creation of new GPU buffer by running the first map of the frame with DISCARD
  • Fixed a bug where a ship would gain strength through doctrines, on reloading a save they would be damaged
  • Fixed a bug where planes destroyed by other sources than air to air combat did not count towards war participation (as an example: static anti-air or destroyed planes in a raid)
  • Raj: Fixed "Mixed Economy" giving resources on all owned states rather than starting states and added coal
  • Raj: Fixed "The riches of the Raj" to check for synthetic refineries as well
  • Raj: Fixed "Acquire new Resources" so it gives the resources to the correct state
  • CTD that could occur with scientists in late game
  • Fixed a bug where a naval supply tooltip would show a much larger number of convoys required then was actually needed
