Two betrayals not spawning enemies

[Fluinol]

After you have escaped the control room and deactivated the first light beam (i dont remember what Cortana calls it to be). The game does not spawn any more enemies.

Anyone else?

[Robert F.]

Which area though? The twin bridge part or the outside of the control room (completely empty except the 2 jackals and elite)?

[Fluinol]

After that area you mention, no more enemies. I keep advancing through the level and no one appeas, flood or covenant

[Worgen_Freeman]

Did you do some sort of speed running trick you were unaware of which despawed all the enemies?

[Fluinol]

Nope, just normal run
