Leviathan Update

ยท 4 min read

I'm excited to announce Rakaly has support for Leviathan! There were some interesting encounters along the way, but in the end, you can analyze and upload Leviathan saves like normal. In keeping with the decaying leaderboard, patch 1.29 has a 20% tax and patch 1.30 has a 10% tax to the number of days required to complete an achievement.

In a way this is Rakaly's 1st patch birthday, as Rakaly was announced the week of the last patch, Emperor, a little under a year ago.

Save Changesโ€‹

There were some changes to the save data. The most exciting change is that negative development is captured:

Negative development is now represented in game Negative development is now represented in game

More testing is needed to pinpoint what subset of actions represents negative development (concentrate development, pillaging (razing excluded)).

Another unfortunate aspect is that positive and negative development actions are summed together so now a country's contribution to a province can be 0 if it was pillaged (?) and then later developed by the pillager.

Positive and negative development cancel each other Positive and negative development cancel each other

Ideally they'd be split into two to more accurately capture dev changes.

The binary format (used for ironman and non-editable MP saves) had migration_cooldown renamed to migration_cost. This is unfortunate as the melter assumes that field names aren't patch dependent, so this is a heads up for those who melt an older save and see a new mechanic. I did check a few 1.30 and didn't find migration_cooldown so I'm optimistic that this issue will be rare.

Also monuments (known internally as great projects) implicitly extended the timeline as some monuments are built long before the 1444 start date:


The -2570.1.1 is a problem as dates and numbers are indistinguishable in the binary format as they are both stored as the same type. Rakaly had some heuristics to detect realistic dates, but these prehistoric monument dates avoided detection due to being such outliers (the previous record holder for oldest date was a monarch with a birth_date of -79.1.1). As always, a fix was found with additional code for context, but it certainly presented a speedbump.

Speaking of monuments, this is something I'm looking at exposing in Rakaly.

Wasteland Terrainโ€‹

What is concerning is that I use a runfile to export a list of province terrain by assigning each terrain to a certain nation. Below is a snippet showing how to assign every hill province to France in pre-1.31:

every_province = {
limit = {
has_terrain = hills
cede_province = FRA

Executing this runfile in 1.31 results in a crash with the following error:

Trying to set owner FRA on wasteland/lake province 2200

This is due to province 2200 (Suleiman Range) being impassable terrain (ie: a wasteland). The fix is easy enough, only assign non-wasteland hills to France.

every_province = {
limit = {
has_terrain = hills
is_wasteland = no
cede_province = FRA

But this makes me nervous that this could impact the Eat your Greens achievement that requires one to own all grassland provinces as Kale as the achievement logic looks like:

owns_all_provinces = {
continent = asia
has_terrain = grasslands

And unless owns_all_provinces filters down to all ownable provinces then there is a chance that Eat your Greens is impossible to complete in Leviathan if it requires one to own wasteland provinces.
