GID calculation for collections of images off by one?

else if (tileset.tilesLength > 0) // If the tileset is a "collection of images" with explicit tiles.

I use a mix of terrain tilemaps from a single image, and several "collection of images" types.

Had problems with an object being in the object-array but not rendering, and also causing heap corruption when unloading.

Patched it to:

else if (tileset.tilesLength > 0)
{
    uint32_t greatestID = 0;

    for (uint32_t j = 0; j < tileset.tilesLength; j++)
    {
        if (greatestID < tileset.tiles[j].id)
            greatestID = tileset.tiles[j].id;
    }

    tileset.lastGid = tileset.firstGid + greatestID;
}

That seemingly fixed the problem. The object started rendering again and the crash on exit went away.
