 # fireSense_dataPrepFit (development version)
 
+- Fixed: `nonflammableLCC`'s default (`c(0, 20, 31, 32, 33)`) missed SCANFI's rock/exposed code
+  (`30`), so rock entered fits as flammable non-forest. The default now comes from
+  `fireSenseUtils::fireSenseNonflammableLCC`, the single source of truth `makeFireSenseLCC()`
+  also uses. Needs `fireSenseUtils@development (>= 0.2.3.9060)`. Version 1.2.0.9017.
 - New parameter `fuelCovariates` (default `"domSecOther"`): `prepare_SpreadFit()` now builds the
   spread covariates as `dom_agb_<class>`/`sec_agb_<class>` (the ELF's two fuel classes with the
   most total treed AGB), `other_agb` and `treedWetland_agb`, chosen once per ELF by the new

 <p>Vegetation, land cover and stand age are snapshots, one per year in <code>P(sim)$dataYears</code> (default 2000, 2010, 2020).
 Each year in <code>P(sim)$fireYears</code> uses the snapshot at or before it, so no fire year may precede the first data year, and every data year needs at least one fire year.
 Climate is annual and is matched to the year of each fire.
