I was doing some mech conversion and noticed the following errors:

LOCATION: Appendix: Clan Invasion, Light Omnimechs, Page 223

ERROR: The Fire Moth Prime's 2 ER Medium Laser group is listed as 6 damage.

CORRECTION: The weapon group should be 5 damage, per the Damage section on page 81. (14 TW Damage) / 3 = 5 (rounded up). The Stormcrow (page 226), Timber Wolf (page 228), Bashkir (page 231) and Scytha (page 233) all have an identical weapon group correctly listed as 5 damage.

LOCATION: Appendix: Clan Invasion, Light Omnimechs, Page 224

ERROR: The Adder Prime is missing its Flamer.

CORRECTION: Add weapon group. [Flamer, 1 (or H), E, H, T, +1, +1, -, -]

LOCATION: Appendix: Clan Invasion, Light Omnimechs, Page 224

ERROR: The Adder Prime is tagged as a Brawler.

CORRECTION: Presumably it should be tagged as a Sniper, being equipped with two ER PPCs and a Targeting Computer.

LOCATION: Appendix: Clan Invasion, Light Omnimechs, Page 224

ERROR: The Adder Prime is listed as 1/2 for Punch/Kick damage.

CORRECTION: Punch/Kick damage should be 2/3, per the Physical Attacks Table on page 43. (35 tons) / 30 = 2 (rounded up). (35 tons) / 15 = 3 (rounded up).

LOCATION: Appendix: Clan Invasion, Medium Omnimechs, Page 225

ERROR: The Viper Prime is listed as 1/2 for Punch/Kick damage.

CORRECTION: Punch/Kick damage should be 2/3, per the Physical Attacks Table on page 43. (40 tons) / 30 = 2 (rounded up). (40 tons) / 15 = 3 (rounded up).

LOCATION: Appendix: Clan Invasion, Medium Omnimechs, Page 226

ERROR: The Nova Prime is listed as 2/3 for Punch/Kick damage.

CORRECTION: Punch/Kick damage should be 2/4, per the Physical Attacks Table on page 43. (50 tons) / 30 = 2 (rounded up). (50 tons) / 15 = 4 (rounded up).

LOCATION: Appendix: Clan Invasion, Heavy Omnimechs, Page 227

ERROR: The Hellbringer Prime is listed as 2/4 for Punch/Kick damage.

CORRECTION: Punch/Kick damage should be 3/5, per the Physical Attacks Table on page 43. (65 tons) / 30 = 3 (rounded up). (65 tons) / 15 = 5 (rounded up). The Thunderbolt on page 162 is the same tonnage and has a Punch/Kick of 3/5.

LOCATION: Appendix: Clan Invasion, Heavy Omnimechs, Page 228

ERROR: The Summoner Prime is listed as 2/5 for Punch/Kick damage.

CORRECTION: Punch/Kick damage should be 3/5, per the Physical Attacks Table on page 43. (70 tons) / 30 = 3 (rounded up). (70 tons) / 15 = 5 (rounded up). The Archer and Warhammer on pages 163 and 164 are the same tonnage and have Punch/Kick of 3/5.

LOCATION: Appendix: Clan Invasion, Assault Omnimechs, Page 229

ERROR: The Gargoyle Prime is listed as 3/5 for Punch/Kick damage.

CORRECTION: Punch/Kick damage should be 3/6, per the Physical Attacks Table on page 43. (80 tons) / 30 = 3 (rounded up). (80 tons) / 15 = 6 (rounded up). The Awesome on page 165 is the same tonnage and has a Punch/Kick of 3/6.

Possibly the Punch/Kick errors are a result of the confusing wording on how to round in the Physical Attacks Table on page 43 (emphasis mine):

* Round up the end result to nearest whole number.

My error reports assume we should be rounding up. If we should be rounding to the nearest whole number, then these Clan mechs are correct, but some of the Inner Sphere ones are wrong.
