I didn't know there was other loops.. or maybe you're talking about those that you can't take advantage of (or use a bit of luck at each loop) ?The only one of some importance is on the third encounter deck of the Hobit where you have only treachery cards in the encounter and you cycle them for ever...
With the loop I know of, you can break it anytime you want, and do whatever you want, so usually, all your scenario end with a score of 40 or 50 or less with victory point, because you usually need 4 or 5 turn to play it. (you need 4 cards for the loop but will bring you nowhere, 5 to do whatever you want).
