Frequency: whenever i succeed in reducing Tenzens hp to 15%
Character Name: Aerymitsu

World: Asura
Main Job: Red mage 75
Support Job: Dancer 37
Area and Coordinates: Sealion's den H-6
Party or Solo: Solo with trusts
NPC Name: n/a
Monster Name: Tenzen
Steps:
1. able to enter battlefield and fight against tenzen
2. when i manage to get his hp to 15% it ends the battle and instead of triggering a cutscene which guides say is automatic, it teleports me back out to sealions den with the rest of my trust and without any way to reach Al'taieu or to progress in the chains of promathia missions.

Not a bug, managed to resolve it by having a friend help me clear it and managed to trigger the cutscene, apologies.
