The rest of Mordor has lots of towers and camps, so no need to have them in Nan Ungol too. But if you want to hire a spider for the achievement and can't because you won't find a single pit, that's frustrating. </p><p>Perhaps they need some special kind of condition to spawn, which is never met in Nan Ungol? </p> <div style="text-align:center; background-color:#3caa25; border:2px ridge green; width:18em">   <font color="#cebc1e"><span title="Ffets">ᚠᚠᛖᛏᛋ (ContentMod)</span></font>   </div>

<p>Well spotted. There is an off-by-one mistake in the spider pit structure file (or, rather, the warg pit file, which it derives from) which means that they can never generate, in any biome at all. And neither can warg pits. Oops... </p>
