They’re not meant to be impregnable fortresses.
either make chests able to be destroyed with regular weapons semi easily, or make them unable to be locked. the chests are meant to hold items, not be fortresses.
everytime someone raids, you always see a bunch of locked chests that havent been blown yet.
put your chests behind a locked door, and that should give security. chests themselves shouldnt be more secure than a room.
fix this to make raiding more appealing because its not worth it at all.
