[BUGS] Save Position, Multiple, 1 Game Breaking

Requirements
Save Pylon at any of the POIs/bases/shelters
Good gun that destroys door fast (for BUG 1)
Close enough to run into said door fast (for BUG1).

See there are a few bugs with POI Save Pylons.

Bug 1: The positional save is not immediate for your character/player. Until you see that Restore Point Created, it has NOT saved your positional data. This allows you time to take some actions, or get into places you may not be able to get out of (example be fast enough to blast a steel door and run inside before that message and boom, saved inside building).

Bug 2: Both save slots get written when using Pylons (whereas exit from your ship only overwrites one slot).

Combine those, and you have a recipe for stuck inside a building, unable to use weapons, game.broken.

Note: can be useful at times though to get into good repeatable screenshot positions for when changing graphics options to compare.

last night, before the patch, my ship got stuck into a cave.... my heart dropped as my shields and ship was taking damage quickly. After about 4 minutes of repairing as fast as I could multiple times, I was able to get my ship out of the cave and did not lose my ship.
