This occurred about two days ago. Two of the random exploration areas stacked on each other at the same spot. Both were operable, one led to a starving kobold bandit and the other to some nightmare bats. This occurred in the foothills near the Delving mistpath.
On a similar note, the transitions to two invasion battlefields stacked on top of eachother a week or so ago.
I have noticed this also. This was outside the scar cave.
