You've chosen to join with Bartolomeu, made your peace with Holland, taken Chico Cois back to Cuba, and taken a job from Henry Morgan to find out why Bartolomeu hasn't returned from Vera Cruz. After tracking him down to the tavern, he tells you he's going to scout the fort to check if the Aztec treasure is really there. At night, you watch him jump down to a tent, then you help him take on the guards.
Bartolomeu is only armed with his fists. So unless you get in there really quickly, he's going to stun some of the guards. Stunned guards aren't recognised as being dead for the purposes of a 'LAi_group_SetCheck', even if you finish them off with a sword. (See How not to kill guards at El Morro for another example of this.) So the quest never proceeds to case "relever_bart3".
@Bartolomeu o Portugues: perhaps equip Bartolomeu with his "BladeBP" at case "relever_bart2". He can then kill guards instead of stunning them, and that scene should work much more reliably.
