If the problem is with lack of adventures, go to the adventure board and queue a full task bar with requests for an adventure. One will usually pop up from the eight attempts. If it doesn't wait until the mailman has been the next day and queue eight requests again. This always works for me, though sometimes the adventure is rather pathetic - catch five frogs or something similar. If all else fails, the board should have new adventures the next time you visit that country. As someone has already said, France is the place where this problem is most likely to occur, but there are plenty of adventures to complete level 3, some (non tomb raiding) adventures will respawn occaassionally too.
