Hello Admirals,

There is ongoing work for the next major update, but we decided to offer an intermediate, very important update, which optimizes the stability and fps performance of the game. Please read:

*v1.6.1.5*

• Fixed memory leak issue which could cause severe fps drop, usually in campaign battles. This problem could happen when players were starting a battle and did not start the battle immediately but waited for some time in the preview window or made an alt+tab and moved their mouse, something very natural during long play sessions. Progressively memory consumption could reach unmanageable levels and cause huge fps drop.
  
• Fixed a bug causing allied minor nations to attack their allies to gain back their lands.
  
• Fixed a rare code exception which could cause a campaign’s turn to freeze, while moving vessels.
  
• Part collider optimizations, affecting also positively the auto-design part placement logic.
  
• Overall auto-design optimizations, resulting in even more effective ships made by the AI.
  
• Auto-resolve fine tuning, fixing a case where the winner could be wrongly overwhelming too much the opponent, with no losses.
  
• Other minor fixes.
  

Uploaded optimized build including:
- Further optimizations in fps performance.
- Further optimizations in auto-design.
- Optimization in Battle AI logic.
- Fixed issue which could cause a sold ship to a minor nation to not be fully transferred, so it would appear in player's fleet instead.
You must restart Steam to get the update fast.

Uploaded optimized build x2 including:
- When a minor nation attacks you, the special mission that creates a naval invasion is now happening immediately, without the need to previously have fleets in the area, as before. The government will ask you if you agree to attack and if you agree, you will need to send ships in the mission to invade the province that the minor nation uses as base of operations.
- Ships that previously were sent to be repaired randomly to other ports, when their supply port became unavailable, will now be sent to the next nearest port, in a more efficient route.
- Other fixes/optimizations.
You must restart Steam to get the update fast.

Uploaded optimized build x3 including:
- Minor nations will attack with less frequency when they want to take back their own lands. It should be more manageable now, but we need further feedback.
- Fixed border issues in territories near Canada which could create bugs in the land army distribution (e.g. too small army to defend. etc.).
- Fixed potential minor issue creating an empty AI task force for some turns (e.g. when all ships of the task forces got destroyed or were sent for repairs, they might have caused such a problem).
- Fixes in temporary issues of auto-design, which now should be much faster and effective.
- Fine tuning in ship flooding mechanics with the aim to sink faster ships with high structural damage.
You must restart Steam to get the update fast.

Uploaded optimized build x4 including:
- Various auto-design optimizations.
This is the last stable build before v1.7. You must restart Steam to get the update fast.

IMPORTANT NOTE
We added v1.6.1.5 Optx4 in the list of previous stable builds. It is advised to switch to it, if you do not want to miss any saved data before the release of v1.7 major update.
