Loot chest respawn timer

[Narelle]

Unless it is different on PS4, any chest can be destroyed. Here is even a player mentioning they do it regularly:

Corrupted Powder no longer dropping in The Summoning Place chests

chests can still bug out and not spawn anything in at all… in which case you need to destroy the chests… I make it a habit to destroy them after looting them just so it re-spawns properly.
