[1.14] Almanac not showing correct speed for AI ships

[shvaks]

Start time: 1900


Player Nation: Japan


Start options: Slow aircraft development, manual build of legacy fleet, 90% research rate


Issue: The almanac and the data window shows different speed for AI ships. In the attached example, The Almanac shows that the Charles Martel has a speed of 18 in the list, while the detailed ship data window shows the Charles Martel has a speed of 21. This bug does not affect player nation.

Expected behavior: The almanac and the detailed data view should provide the same speed data for an AI designed ship. I understand it could be a design choice to give player false ship data in almanac to simulate inaccurate intel, but the data provided in different windows should be consistent.  

How to reproduce the bug: The bug shows up in a normal playthrough so playing the game and the bug should show itself.
Game version: 1.14

Almanac speed is still wrong in 1.18.

New game: 1920, Germany, all settings at default.

To reproduce:

start new game (as above or likely any other combination)

Open almanac.

Compare speed as given in almanac and as given by 'data' (right-click on the line, select 'data') screen for a few classes.

More than 50% of the ship classes (of all foreign nations) are off.  Many just by 1 knot.  But a number are ... really off.

Looking through those with greater discrepancies, the following emerged:

• The speed as listed in the almanac is from the respective "EnemySpeed" entry in the save game file of the class.  This is almost sure the correct info.
  
• The speed shown in 'data' is from "OSpeed" entry.  This is almost sure to be incorrect.

Proposed corrective action: Let the speed in the "data" screen come from the "EnemySpeed" entry (instead of the "OSpeed" entry) unless it is our vessel.

Most of the "speed" entries are clear in their meaning

• EnemySpeed --- what other nations think the speed is
  
• DesignSpeed --- what the ship was designed to reach (if all calculations were right etc)
  
• Speed --- the maximum speed the ship can make
• OriginalSpeed --- what speed the vessel could make originally, before bulges were added or the engine replaced etc.

But what "OSpeed" means is unclear --- and the values do not make any sense to me.

Data: All cases in my completely new game where the difference was more than just 1 knot off

I can confirm this. The problem hasnt been solved.

... I'd like to add:

As soon as the player gets his hands on the blueprint (intel event), he should be presented with the correct values everywhere in the game!

Yes, I do agree with this - thanks.
