Defendable objects are wonky and can stack on top of each other sometimes. How many defendable objects were listed in the nav bar when you ran the mission? Even if the map only allows for 2 objects to be placed in the back, you can place more, up to the map's limit. The extras will be pushed out of the back into another area. This is what should happen. However since defendable objects can be wonky, it may have allowed them all to spawn in the two available back locations.

Well I got the defendable object part to work, but there are still spawns throughout the map. Any ideas as to how to get the destructable object to do the same? Wanna make an endurance run map for my scrapper, and see how long he can last in a senario like this. It's just that I don't like the enemy group the mission I came across has.
Nevermind, I finally figured it out. Was a problem with the Architect's mechanics
Was browsing through missions today and came across a mission that has every enemy in the back room of the map. According to this mission, there are defendable objects, destructable objects, and a collection. The mobs surrounding the two objects were HUGE. When I jumped in even more came running into the room after the defendable object was destroyed. The map details say that only 2 defendable and 2 destructable objects can be placed in the back. Anyone know how this is done?
