i've met strange bug that sometimes was giving me my bolts back after the trap was destroyed no matter what the distance was.
there is two times i saw this bug in video - at the start and 4:37
honestly idk why this bug happens
I noticed this in my gameplay as well.
I think it may have something to do with the 'ricochet' mechanic.
Its rare, but bolts do bounce; in particular off armor (for crossbow bolts specifically)
It's also not beyond reason to think that the trap exploding throws the bolt back close enough to you to retrive it with you magical bolt retrieving abilities; but likely not working as intended.
