prototypes/compat/krastorio2.lua never runs. The only require for it is commented out at data-final-fixes.lua:2. If you uncomment that line, the file fails with two separate errors.
Reproduction: uncomment data-final-fixes.lua:2. The load fails at line 95. Apply the fallback shown below, and the load then fails at line 250.
Bug 1 — wrong prototype type for galvanization-science-pack
Line 95 reads the pack from data.raw.tool:
order = data.raw.tool["galvanization-science-pack"].order
Paracelsin declares that pack as type = "item" in prototypes/items.lua:223, not as a tool. The lookup returns nil.
outer-rim/prototype/compat/krastorio2.lua:95: attempt to index field 'galvanization-science-pack' (a nil value)
Line 103 does the same for golden-science-pack, and that line works, because secretas declares that pack as type = "tool". A fallback fixes line 95:
order = (data.raw.tool["galvanization-science-pack"] or data.raw.item["galvanization-science-pack"]).order
Bug 2 — undefined global spacecraft
Line 224 assigns to spacecraft.ingredients. The variable spacecraft never receives a value. A search of every .lua file in the mod finds no spacecraft = and no local spacecraft =.
outer-rim/prototype/compat/krastorio2.lua:250: attempt to index global 'spacecraft' (a nil value)
The sibling variables at lines 4, 26, 57, 176, and 177 use one pattern, so a line like this looks missing:
local spacecraft = data.raw.recipe["outer-rim-spacecraft-science-pack"]
I could not tell which recipe it should name. outer-rim-spacecraft-research-data at line 246 is the only outer-rim-spacecraft* string in the mod, and no file declares it as a prototype. The spacecraft tier appears to be absent from 2.3.2.
Line 224 sits at top level. Every user who runs Krastorio 2 reaches it.
Limit of this report
I never got past line 250. Lines 250 to 324 have not executed in my testing. I cannot say that the file works after you fix both bugs. Note that lines 318 to 321 read data.raw.recipe["nitric-acid-barrel"], data.raw.recipe["nitrogen-barrel"], and data.raw.tile["nitrogen-lake"] without a nil check. I did not confirm that those three resolve.
Why this affects other mods
Other mods treat the presence of outer-rim as proof that outer-rim supplies the Krastorio research data items. xy-k2so-enhancements-nulls-fork skips its own xy-golden-research-data and xy-galvanization-research-data when outer-rim is enabled. k2so-cubium-compatibility-fork then selects outer-rim-golden-research-data for a recipe. That item never exists, and the game fails to load:
Error in assignID: item with name 'outer-rim-golden-research-data' does not exist.
At ROOT.recipe.golden-science-pack-cubic.ingredients[1].name
This last error happens with an unmodified outer-rim. It needs no edit to reproduce.
Please either repair the compat file or remove it from the mod. The dead file leads other authors to assume that Krastorio 2 support is present.
Version: outer-rim 2.3.2, Factorio 2.1.14, Krastorio2 2.1.2, Krastorio2-spaced-out 2.0.15.
