If you are not nitpicking, the whole Conclave to elect the successor of pope Clement V did nothing and didn't even reunite for two whole years, from 1314 to 1316. They were so divided on the issues of whom shall be the next pope and where he shall reign (Rome or Avignon) that they stayed separated in little cliqs, either in Avignon, Carpanthra or elsewhere in the region.
Only the regent Philippe, count of Poitiers (later Philippe V) succeeded to lure then in Lyon to force the Conclave, by a mass in memory of Louis X. He had them imprisoned in the Church and had the issues sealed by masonry, without food but daily bread and water, and menace of open the roof of the Church if they didn't come to an agreement. After a while, at the suggestion of the regent, they elected the eldest Cardinal present, who was faking to be in agony. They thought they would elect a dying man and that they could go out very quickly, but they elected Jacques Duèze, whom becomed Jean XXII.
