Dc’d a total of 4 times whilst inside Laz due to server errors so I had to replace myself with someone else effectively losing my orb I had waited for to CD and the Umbral we were on track for.
I really apologize about the server error that cause you a disconnection in the middle of the expedition. I truly understand this can be an inconvenience for you a your group progesion.
My best advice is to contact customer support ; they can take the necesary actions to investigate further in your case in specific, and have an answer for you as soon as possible
