May just be horrible luck, but twice this week 6/26-6/27 had instance crash / all go LD on Bristlebane server after completing raid. Lag / rubber-banding very noticeable both events. Crash was right after opening chest one time, and shortly after dividing up loot the other. Some had LO, some did not. No retained loot, currency, or ach. While we had very rough lag and rubber banding many times before, this was first I think we had instance collapse post win x2 like this.
Highly speculative but since last patch/hotfix (not sure) raid instances are opening to receive players before the old 30s~ hard cap that was in place to prevent issues from zoning in too early...
I didn't get to keep the currency we had earned, yet all my glyph AAs were still gone. How does THAT happen? This was really frustrating and feels like a huge waste of our time.
