Wrong results from getStructurePos?

[mcbq]

Hi

I'm trying to use getStructurePos to find a seed with an outpost near spawn, from looking at the two provided examples I've stitched together the following

#include "finders.h"
#include "generator.h"
#include "layers.h"

#include <unistd.h>

int isValidBiome(int);

int main(int argc, char *argv[])
{
    // Always initialize the biome list before starting any seed finder or
    // biome generator.
    initBiomes();

    int64_t seedStart, seedEnd;

    seedStart = 0;
    seedEnd = 100000000LL;
    StructureConfig featureConfig;

    featureConfig = OUTPOST_CONFIG;

    unsigned int range;

    int regPosX = 0;
    int regPosZ = 0;

    regPosX -= 1;
    regPosZ -= 1;

    range = 200;

    LayerStack g = setupGenerator(MC_1_13);
    int *cache = allocCache(&g.layers[L_VORONOI_ZOOM_1], range, range);

    int64_t s, base;

    Pos outpostPos;

    for (s = seedStart; s < seedEnd; s++)
    {
        base = moveStructure(s, regPosX, regPosZ);
        outpostPos = getStructurePos(featureConfig, base, 0+regPosX, 0+regPosZ);

        //Validate that position is valid biome
        if (!isValidBiome(getBiomeAtPos(g, outpostPos))) continue;

        printf("%ld\n", s);
        printf("%d\n", outpostPos.x);
        printf("%d\n", outpostPos.z);
        fflush(stdout);
    }

    freeGenerator(g);
    free(cache);
}

int isValidBiome(int biomeId) {
    int validBiomes[] = {
        plains,
        desert,
        savanna,
        taiga,
        snowy_tundra,
        snowy_taiga,
    };

    int i;
    for (i = 0; i < sizeof(validBiomes) / sizeof(int); i++) {
        if (validBiomes[i] == biomeId) {
            return 1;
        }
    }

    return 0;
}

which outputs seeds and coordinates, however I've not yet managed to find a correct set where the coordinates actually had an outpost? From looking at the quad_huts file the biomecheck seems necessary, but am I missing something else?

Thank you for your itme
Which outputs seeds

Sorry that the issues haven't been maintained well,
examples like this are in the readme.
