Xotl, it looks like you forgot to update the links to errata documents in both Campaign Operations and TechManual threads.
Also, I've found a couple issues with the recently published BMM errata document (v. 4.2). specifically with this bit appearing on pp. 6 and 14 of the document:
* Collapse: Falling and Displacement [example text] (p. 57)
Fourth paragraph, second sentence
using the Front/Back column of the Hit Location Table.
Change to:
using the Front/Back column of the Punch Location Table.
The first issue is the page number. Collapse: Falling and Displacement section of the example box in question is on p. 74 of BMM, not p. 57.
The second issue is with the content of the correction itself. The fourth paragraph, second sentence of the Collapse: Falling and Displacement section on p. 74 BMM deals with falling damage done to Stinger, which in that example fell from a roof of a collapsing building hex, and landed on a Locust which was below it - inside of that building hex when the collapse begun. According to Falling Damage To A ’Mech rules as they are written now (see pp. 57 and 73 BMM) the Stinger should resolve its falling damage using Front/Back column of the Hit Location Table (applying damage to the rear facing of torso armor where appropriate), and it is the Locust that should use the Punch Location Table to resolve damage taken from its collision with the Stinger, so the correction to Collapse: Falling and Displacement section on pp. 6 and 14 of the errata document would be:
* Collapse: Falling and Displacement [example text] (p. 74)Third paragraph, first sentence
using the Front/Back column of the Hit Location Table.Change to:using the Front/Back column of the Punch Location Table.
Having said the above, I'm not sure if the Falling Damage To A ’Mech rules on p. 57 BMM (and p. 152 TW and p. 44 AGoAC rulebook) are correct. I explained it in detail in this thread:
https://bg.battletech.com/forums/total-warfare/accidental-fall-from-above-damage-problems/ , but long story short - I suspect that if a 'Mech accidentally falls on the back of a prone 'Mech, the damage to the prone 'Mech shouldn't be resolved using Punch Location Table as written now, but just like DFA attacks against prone 'Mechs - using Front/Back column of the Hit Location Table with torso damage applied to the rear facing.
If I'm correct then we would need the following changes to the errata document:
1. Falling Damage To A ’Mech rules on p. 57 BMM (as well as p. 152 TW and p. 44 AGoAC rulebook) would be changed to account for the case of a 'Mech/unit dropping on an already prone 'Mech. For example in BMM the errata would be:
Falling 'Mech Hits Target (p. 57)First paragraph, third sentence
to the target ’Mech using the Punch Location Table.Change to:to the target ’Mech using the Punch Location Table if it is standing, or to the target's 'Mech rear using Front/Back column of the Hit Location Table, if it is prone.2. the correction to Collapse: Falling and Displacement [example text] (p. 74) section
would have to be removed entirely, since the pre-errata BMM text is actually correct, due to the fact that the sequence of resolving building collapse in the example would cause the Locust to be already prone when Stinger landed on top of it.
Edit: I believe I've found yet another issue with the new BMM errata (pp. 2 and 14 of the document):
* Reversing (Flipping) Arms (p. 24)
Third paragraph, after the second sentence insert the following:
A ’Mech cannot punch or make physical weapon attacks while its arms are reversed.
Shouldn't this new rule make an exception for Talons? They are covered in the Physical Weapons Attacks section of the book (p. 38 BMM), but I don't think that flipping arms should prevent attacking with them, since it doesn't prevent "regular" kick attacks.
Edit 2: I've also noticed an error on p. 6 of the TechManual v5.0 errata document:
Hesiod Wheeled Support Vehicle [example text] (p. 75)change to:Hesiod Wheeled Support Vehicle [example text] (p. 128)
