The game should optimize load times by caching the terrain and resetting the traps and guards.
I had this poor guy who took a minute and 30 seconds to reload into my outpost, and then died 30 seconds in and had to wait a minute 30 to play again.
He spent more time in loading screens than playing the game. :( He must have been on an original PS4.
Seems like the game shouldn't have to reload the whole outpost if they're just reviving.
