The check your event log:
1: press Options on your controller, it’s the small button to the right of the trac pad.
2: Scroll down to “Event Log”
3: While in the event log menu, you will see a bunch of check boxes and a blank page below,
Make sure all of the boxes are checked, and press the Square Button to start loading in your event log. It may take a minute or two to load.
4: Scroll down your log and see what happened.
If nothing shows up, either too many events occurred after your body was looted, and the logs deleted the log of what happened, or it simply didn’t record what happened. It’s happened to me before when one of my thralls decided to take a lava bath and his death wasn’t recorded.
And Rubber banding is when the game jumps someone where they aren’t supposed to go because of Lag.
They could also have Meshed your base, not saying it’s possible but I’m not saying it’s impossible either,
What meshing is, is whenever a player finds a way to get under the map, and can therefore ignore defenses and walk right into your base
Hope this helps
And good luck on conan
