Stuck on RoV 'Sin' mission: in-game bug.

Hello,

I was progressing through the cutscenes on Rhapsodies of Vanadiel 3 - 7 - 4 Sin (Mission). I made it through a couple of the cutscenes on this mission and then my connection dropped. I am now unable to progress past this mission or continue past the final cutscene. Clicking on the Desuetia - Empyreal Paradox no longer progresses the mission. My mission log shows the Sin mission active.

Update November 10, 2019
This is still an issue. Can this issue please be resolved. I cannot progress in the game. It has been over a year since this issue was first reported to a GM.

also, i did go to a mystic retriever in Jueno and the issue did not resolve.
