I too had this query, good to see its been answered (2015!), though just one thing extra I wanted to ask for clarity:
Sticking with the Jump Core example as it needs 2 actions, If my character was for example the Teleporter Chief (and therefore no action discounts) but has 1 Engineering discount, does that discount apply to each action used on the jump core. Therefore, 2x actions used means 2x less engineering skills needed (so 3 in total for the JC repair) OR regardless of the fact it costs 2 actions, I can only apply the discount once during each repair so it always costs 2 actions and 4 engineering skills for that character?
Just here to confirm that any order placed on The Game Crafter is already locked in, so no one should worry about getting Gate. 🙂
Regarding everything else, I have no idea. I'm sad about it, too, and I hope that whatever is going on, there a good solution for him and his somewhere.
There were four expansions and one extras pack for Iron Helm. He was indeed in the middle of several other projects, but the shuttering seems to have been as abrupt as the last day of Saigon, so I'd expect whatever was left on the table to sit there indefinitely.
