Glad to be of help, Xotl! I've spotted another couple of entries in the book that need fixing.
Page 71, Levels, second paragraph: "If the level of the hex to be entered is one level lower than the level of the skidding ’Mech’s current hex, the level change has no effect on the skid. If the level is one or two levels lower, the change has no additional effect on the skid." Not really an error, but the first sentence becomes kind of redundant.
Page 72, Combat within buildings, second paragraph: "Unlike standard combat, ’Mechs in the same building hex (and even at the same level in the same hex) can attack one another." Two mechs at the same level in the same level in the same hex would violate stacking limits, I believe.
Page 72, Building Combat Diagram-sidebar: Here's another example that first appeared in TW (p.176). As written, the target number modifiers for the attack on the Warhammer and the Locust are incorrect (the Warhammer in the example is at short range, for example). The example with the Wolverine is correct, however.
Page 73, Collapse: Movement-sidebar: Another example from TW that needs some rewording (TW p.177). In the MM sidebar, hexes D and E have a CF of 8, but in the hex collapse section the CF is listed as 7. In the TW example, the mech collapsing the two hexes was a Marauder, but in MM it is an Archer. For the example to work, the CF should be changed to 7.
Page 74, Collapse: Building Collapse-sidebar, second paragraph. The Archer is at one point listed as doing a base damage of 0.7, only to have a base damage of 0.8 later in the same paragraph. The base damage should be 0.7.
