Just to let you know, the current, provisional wording on errata for this issue is:
"1) Under Game Rules, second bullet point, change the last sentence to read: “For non-’Mechs, these critical hits are applied as sequential motive system or flight stabilizer hits and then (after these are all marked off) transfer inward to the engine itself, destroying the engine immediately on the first hit.”
Does that address all the issues?
Hmmm...I'm afraid I don't think so. First of all, if you just change that last sentence, the
first sentence still instructs you to roll "on the unit's appropriate Determining Critical Hits Table" -- vehicles, which normally only take at most one critical hit per opportunity, would still need to be explicitly pointed back to the "standard" table on TW p. 124 if a supercharger malfunction is to generate the chance for up to
three "critical" hits.
And second, it's not wholly clear how these "sequential" hits are supposed to interact with
previous motive system damage. As I understand it -- and correct me if I'm wrong, though the current wording of rules plus errata would seem to support my view --, any given motive system hit can normally readily happen
multiple times; despite the presence of boxes on the record sheet suggesting otherwise they are
not actually "marked off" as they occur. Thus, for example, a second 'minor' hit doesn't scroll up to 'moderate' just because a first one happened earlier...
...which of course means that the worst a supercharger failure can technically inflict on a ground or naval vehicle is one minor, one moderate, and one heavy motive system hit. This may reduce its MP to 0, but won't suffice to technically immobilize it, let alone kill its engine.
