I. Summary
If TRO Clan Invasion "inherited" the problems with Kingfisher from TRO 3058U described in the "Detailed Explanation" section of this post (bellow), then you need to make the following changes:
1. Change to both TRO Clan Invasion and the current errata document for it:
Kingfisher (p. 73)
Under “Alternate Configuration H”, under the second Double Heat Sink listing change the number of Critical spaces from 6 to 4 and Tonnage from 3 to 2. The upcoming reprint will likely also require changing "3 Double Heat Sinks" to "2 Double Heat Sinks" in that line.
2. Change to TRO Clan Invasion only:
Kingfisher (p. 72 or 73):
Under "Weigh and Space Allocation" change both instances of "Double Heat Sinks" to "Double Heat Sink".
--------------------------------
II. Detailed Explanation
II.a First change
From the 2019-12-06-v2.0 version of the errata document:
Kingfisher (p. 73)
Under “Alternate Configuration H”, change the second Heat Sink listing from 2 Double Heat Sinks to 3 Double Heat Sinks.
I believe the above erreatum may be incorrect. I don't have TRO: Clan Invasion, but I do have the 2006 FanPro edition of TRO 3058U which has entries for some of the same 'Mechs (including Kingfisher). In that TRO the second Heat Sink listing under Alternate Configuration H of Kingfisher is as follows:
2 Double Heat Sinks | (Location) RT | (Critical) 6 | (Tonnage) 3
This is obviously incorrect, as two Clan double heat sinks take up 4 Critical slots and weigh 2 tons, but at the same time the total mass of pod-mounted equipment listed for this configuration is 25 tons, while Kingfisher has only 24 tons of pod space available.
II.b Second change
In Weight and Space Allocation section both Right Leg and Left Leg lines list "Double Heat Sinks". They should list "Double Heat Sink" instead, since each leg has only enough free critical slots for one Clan DHS, and because Kingfisher has 17 fixed DHSs, and 360-rated engine, which, according to TM p. 53, means that it should have only 17 - (360/25 rouged up) = 3 fixed DHSs. One of them is listed in Right Torso, so both Right Leg and Left Leg should have one fixed DHS each.
Of course since the above corrections are based on an old, out of print TRO, which I only suspect may have an identical stats for the Kingfisher, I'm not entirely sure if the same correction applies to TRO: Clan Invasion, and I would be grateful if someone who has access to TRO: CI checked them for me.
Regarding the first change, I believe that the error in the errata document (if it indeed an error) might have been caused by the fact that the record sheet of the Alternate Configuration H of the Kingfisher should list three, not two, Double Heat Sinks in the right torso. But this is because one of them is fixed, not pod mounted, and as such is listed in the Weigh and Space Allocation section of the TRO entry dealing with fixed equipment and critical slots, and not under the Alternate Configuration H.
Finally a word for moderators and everyone else who doesn't like seeing anything that isn't strictly an errata report in the errata thread. Sorry for posting the "Detailed explanation" section at all. I'm aware that as a general rule we are not supposed to discuss errata outside of the Errata Discussion Thread, but since I based my report on an outdated book, I decided to include it both to make it easier for Battletech veterans who own TRO: CI to check if the above report is correct and to let newer players know that this particular report may not be in fact applicable to TRO: CI at all. I plan to delete the entire "Detailed explanation" section (and appropriate parts of the "Summary" section) as soon as someone who owns TRO: CI lets me know which problems I listed above are in fact applicable to TRO Clan Invasion.
