fixed bug that was pre-whacking custom item

my careful code wasn't firing because an overly abusive remove based on find was whacking it; now instead i whack only the expected pieces that start with fmc_ in the loading dock, thus avoiding trashing anyone else's junk that happens to be floating around in there, but more specifically avoiding removing custom regardless of what type of item it is (unless it's the expected link).
