when i followed Dogmeat to west of Vault 81, down to a tunnel then saw a rag bed near a campfire and there has a mine on the bed...

i tried to cook food by this campfire but nothing happened (press E on it), i tried to disarm the mine on the bed but also no effect until it blew up almost kill me ....

i felt angry ....because this seems like some kind trap that only torment player for fun in malice .
