AJSarley223: I've got a soft lock issue. It's in the Reboot arc, in the coolant room where the corpse holding the key to the reactor is found; they're clipped entirely through the wall (I can see a piece of a shotgun shell and a Neuromod sticking out). When I go to pick up the items, the corpse falls out of the world.
= SPOILER ALERT = I assume this is where the key is found because it's the last non-locked spot in the room I checked: in the crawlspace below the floor.
I assume this is Talia Brooks' body (on fire)? There's a few things you can do.
1. Have you tried hitting with the wrench or using gloo? I've sometimes found that to force bodies back in bounds.
2. If you leave the Power Plant, then use a security terminal to track the body and re-enter, it might place the body back in bounds. This has worked for me with a few troublesome bodies like Nicole Hague and Rich Ivers.
3. if you have the neuromods to get Remote Manipulation, you
might still be able to loot the body through the floor.
4. Do a full map reset. Leave the map and make a regular save. Go to your saved games folder. Should be something like "C:\Users\YourAccountName\Saved Games\Arkane Studios\Prey\SaveGames" (I don't have the game installed atm so some of the file/folder names might be off). From there pick the folder with your campaign slot, and the folder for that save you just made. It should be the most recent one. Look for something like "powerplant.level" and drag it out of the folder, like to your desktop. Restart Prey and enter the Power Plant, this will force the map to reset. Just skip past everything you can and get straight to the body. Hopefully it's reloaded properly. Loot it, then go back and exit. Save again, then go back to the folders and replace the original "powerplant.level" back into your folder. The one that's currently in there is the regenerated one with none of your progress, so overwrite or delete it. This is the method most people have to use to get Kirk Remmer to load properly.
