Harnmaster 3 - Combat 4
Quilt Leggings WT 9,2 and PR 184d.

It should be WT 13,2 and PR 176d. It has the same coverage as any other Leggings so it should weight the same as Tunic (that have the same Coverage as Leggings in HM3).

Edit: I should be mentioned that the HM3 Armour has more issues than this. The list is build upon the following coverage percentage:
Skull 4%, Face 3%, Neck 4%;
Shoulder 4%, Upper Arm 6%, Elbow 2%, Forearm 5%, Hand 4%;
Thorax 12%, Abdomen 12%, Groin 1%
Hip 9%, Thigh 14%, Knee 3%, Calf 10%, Foot 6%.

Material (WT/PR):
Cloth (0,1/1d), Leather (0,2/4d), Quilt (0,3/4d), Kurbul (0,25/5d), Ring (0,4/7d), Mail (0,5/15d), Scale (0,7/10d), Plate (0,8/25d).

Anyone who can count can see that 1% is missing from the list. If we assume that most of the armour table is correct, the missing percentage should be in a leg location (there is only 43% legs, counting groin, it should be 44% according to all leggings armour). To avoid changing the entire table (changing % for Thigh or Hip would cause other issues for Hauberks for example), the easiest fix is to increase the Foot percentage to 7%. This change makes only the shoes/boots armour to be wrong, but changing anything else would make more items wrong.

Shoes: WT 1,4 / PR 28d
Calfboots: WT 3,4 / PR 68d
Kneeboots: WT 4,0 / PR 80d

In this example, I changed Foot for the reason that in HM1, Foot percentage was 7%. In HM1 Calves was 12% so I could go there as well, but then more armour parts would have to change.

Perhaps not the most important issue, but worth mentioning here if anyone who doesn't have HM1 but still want to figure out the formulas and create their own armours.

There were, I tell you, many a joust and many pretty feats of arms.

A chivalric episode, ... adds a high light to the scene. The tide had come in and the river was no longer fordable and scarce passable, when a French Knight in Phillp's army rode up along the bank and shouted across to know if there was not some English knight who would come over and joust three courses for the love of his lady. An Englishman from the north country, Sir Thomas Colville by name, heard the challenge, mounted his horse and plunged into river at peril to his life. ... he reach the farther bank safely. The gallants ran two courses. At the second the Frenchman's shield was broken.

Keep in mind there were no fences or walls seperating the horses and they did come within melee range of each other. Horses have no objection to get close and will even fight other horses Stallions will fight to establish breeding rights and mares to estable rank in a herd. So horses will charge other horses, I would suggest that the side bar paragraphs under Mounted Charges should be ignored.

It may be natural for a horses to fight each other, but I've yet to see or read any evidence of horses charging headlong towards each other even for breeding rights in a natural setting. When horses hight I have seen documentaries horses kick stomp and bite eacjh other but never galloping headlong at each other (of course doesn't mean they dont). There are also several reasons the charge only ended in the gallop rather than going flat out from the onset. The danger of the horse finding a rabbit, gopher or some other blasted burrowing animals hole discouraged the charge over an extended distance.

In your example of the knights you need to remember that the riders would have 1)highly trained horses and more importantly would have made (in game terms) a successful horsemanship roll.

The side bar shouldn't be tossed, rather it helps by requiring a horsemanship roll to make such an action.

I have a sort-of side question: what is the difference between 2nd Edition Harn World and 3rd Edition? Thanks!

Harn 'World'? As far as i know, absolutely nothing at all.

The setting/world has been pretty constant since it, well, for a long time now.

Does the newly released errata resolve the discrepencies concerning HM Religion and Barbarian OMLs?

Do we know if there's any chance the pdf will be updated?

Updated with what? It was just released.

I'm sure Columbia Games will eventually reflect the errata in the affected products, but I have no idea about the time frame required for that.
