I was the one who started the discussion on IFR+Corpse Lake. I gave two examples to try and explain what I thought was the ruling (which KTOM agrees with). Other than the, "influence paid for cost is not a triggered efffect" example, I also gave the example of using Seasick to cancel a triggered effect. When you cancel a triggered effect with Seasick, the cost is not refunded because the cost is not the triggered effect.
You want FFG to reverse the ruling that a Cost is not a Triggered Effect? I just don't think this will happen. The best you can hope for is an Errata on IFR, which wouldn't happen until the next FAQ update. So, send FFG e-mails if you want them to errata the card, but I wouldn't be to hopeful. Until they do, it works exactly how KTOM explained it a couple posts ago.
