[Solved] Incomplete Deployment Data Causes Hang

[The Reaver of Darkness]

In a mod I made a change to the itemSets on one particular rank on one deployment, and the mod ran fine but attempting to get into a mission with that UFO caused the game to hang. With some trial and error I discovered that if I provide data for the itemSets without providing data for the rank quantity, the game hangs.

This code will cause the game to hang:

Code: [Select]

alienDeployments:
  - type: STR_MEDIUM_SCOUT
    data:
      - alienRank: 4
        itemSets:
          -
            - STR_PLASMA_PISTOL
            - STR_PLASMA_PISTOL_CLIP
            - STR_MIND_PROBE
          -
            - STR_PLASMA_RIFLE
            - STR_PLASMA_RIFLE_CLIP
            - STR_MIND_PROBE
          -
            - STR_HEAVY_PLASMA
            - STR_HEAVY_PLASMA_CLIP
            - STR_MIND_PROBE

This code will not cause the game to hang:

Code: [Select]

alienDeployments:
  - type: STR_MEDIUM_SCOUT
    data:
      - alienRank: 4
        lowQty: 1
        highQty: 2
        dQty: 1
        itemSets:
          -
            - STR_PLASMA_PISTOL
            - STR_PLASMA_PISTOL_CLIP
            - STR_MIND_PROBE
          -
            - STR_PLASMA_RIFLE
            - STR_PLASMA_RIFLE_CLIP
            - STR_MIND_PROBE
          -
            - STR_HEAVY_PLASMA
            - STR_HEAVY_PLASMA_CLIP
            - STR_MIND_PROBE

Am I just supposed to include all of the data that I'm not making changes to? How much do I need to include to avoid resetting values to defaults?

I'm not sure if this relates to OXCE+ or OXC.

Difficult question, because there are exceptions for everything.

But in general:

1. Top-level single-value attributes get inherited from parent

Example: you don't have to redefine a cost of a research topic

2. Going deeper than top-level (e.g. by specifying an array of values) usually removes all old values before new values are loaded by a mod

Example: when you want to add a research dependency, you cannot just add the one missing... you need to specify all of them in the mod... because they get deleted and reloaded...

... same for your deployment question... the "data" attribute is an array that gets deleted and reloaded

PS: same in OXC and OXCE+

Okay I get it, thanks!
