Co-op maps....

Just wondering if anyone else is experiencing issues when trying to start a co-op match? Specifically 'Explosions 101' When I enter this map it seems glitched and no enemies are present... sometimes I will get into the 'hulker' cinematic but then the hulker doesn't show up for the fight... frustrating bug.

We had a problem when we had a full party. The fix we found was by waiting for the 30 seconds to count down all the way instead of manually pushing A to enter the match. Hope it helps.
