Restraining Order and Helping

[whassumattuh]

Tried to find an answer for this and I failed. In a three-player game, Player A ran into a monster that he could beat. Player B used a monster enhancer on the monster and Player A could no longer beat the monster. I offered to assist Player A in exchange for two treasures. The terms were agreed upon. Player B than plays Dead Broke (i.e., the monster now gives no treasures, so I am screwed while Player A gains a level). I play Restraining Order on Player B. Player B then takes back his monster enhancer and Dead Broke and claims, "Hey, Player A can now defeat this monster without your help so he is not eligible to even take your help." Kind of a catch 22. I can't help Player A if he is able to beat the monster, but I can't play Restraining Order if I am not in the combat. I ruled, as the game owner (c:`, that because I was already in the fight, that I would still be entitled to two treasures. However, after the monster enhancer was removed, there was only one treasure, which I took. Did we play this correctly?
