User blog comment:Vanderm/A couple of Lotr mod myths investigated/@comment-25101089-20161211003518/@comment-25101089-20161211005708

Mordor orcs and olog-hai are supposed to attack players below 100 alignment, though the chance decreases as the alignment approaches 100. Trolls are also supposed to have this behaviour, for 100 alignment. And wood-elves, for 50 alignment.

Looking at the code, I have noticed that there is a mistake: while the alignment behaviour is there, it is impossible for it to actually take effect. So while it isn't a myth, you are right that it doesn't happen any more. I suppose I changed the AI code at some point in the past and missed this mistake. But it was an easy fix, and thank you for reporting it.

The Red Mountains are given a 2x generating factor for all ores in the code, but your test seems to support it actually being 1.5x. The Red Mountains are the only biome in the mod which use this code, so it's entirely possible it could not be working as intended. Looking at the code, the Iron Hills are supposed to have This is in addition to the standard ores for each biome, which are the same as in vanilla: (And glowstone ore as well.)
 * 4-block veins of iron, 10 times per chunk, from y = 0 to 96;
 * 4-block veins of gold, 2 times per chunk, from y = 0 to 48;
 * 4-block veins of silver, 2 times per chunk, from y = 0 to 48.
 * 8-block veins of iron, 20 times per chunk, from y = 0 to 64;
 * 8-block veins of gold, 2 times per chunk, from y = 0 to 32;
 * 8-block veins of silver, 3 times per chunk, from y = 0 to 32.

I must commend you on the post. It's a really excellent and well-presented writeup, and your conclusions are certainly justified. Either there is something going wrong with the generation, or it's down to sample size, but in either case I am grateful for your bringing these things to my attention. I would be interested to hear from other people as well.
