I encountered this after 1.2 patch...
One of the maelstrom is "hiding" inside one of the shipping containers. Just next to the other maelstrom choom in the back of the warehouse.
Only way to get that hiding one was to use tech-weapon with 2! pax-mods. Just charge up the gun so you can see the silhouette. 2 pax'es because otherwise that monk goes ranting about killing.
