Heroic Mana Tombs - Wrong Instance ID

I entered a heroic Mana-Tombs in classic TBC, couldn’t kill the first boss, so I switched to a new group.

New group killed 2 bosses, and wiped on a trash pack. (fear)

When I ran back, everyone else in the group was able to zone in, I was locked to my previous group’s instance somehow and entered a different instance. Kept telling me I was locked.

We tried resetting, I logged out, I dropped group, same thing.

I was promoted to lead, now I could enter, the 4 others could not.

Cannot complete daily heroic. instance ID 85356348
