There's probably a way to delete their location data in the save file.

They actually do respawn already just not if they simply exist.

There's something else that "eats" them and they'll respawn after that, but obviously the abyss is not that "something"

That said.

Dasius while you're near here.

You can actually feed multiple swords into the sword pedestal, I do not know if it respawns the crystal, or duplicates it.

You can also still get stuck at the blacksmith shop between them pillars. Please in the next map change/update ensure that the pillars are not physics-based, or remove that one, or move it so the player cannot fit between it or can easily walk through the gap. It's a very very very unnecessary "bug" (glitch/problem)

It only became an issue because the wood pillars used to be non-physical, and in the previous patch and this one, they became and remained physical. Now that they're physical, if you wish to keep them physical, the pillar positions just aren't right, but personally moving it more out, to make the gap large enough to pass through, feels more of a burden cause it'll be in the pathway, though you could move it to center/close to oil so its beside the path but more gap.... but that still might cause an issue since the anvil is physical too, you might end up causing a new pinching location that players can get stuck in.

thus I would say the best answers would be

Remove the pillar (it's not really needed for immersion sake. The overhang can just be attached to the house, if not already, and then it sits propped up on the far off corner/pillar - the one near the house is redundant for the house's corner)

or

shrink the pillar, and angle it, make it a support-board that is just in the corner of the wall/roof and tarp/overhang - this way it can remain physical, be out of the way, and prevent it from locking a player up, forcing them to have to reset position data
