Me and my dad were playing Tekkit classic and we were mining a bunch at bedrock with destructive catylists. Well my dad calls me over to check something out, and to my surprise it was a chest with bedrock around it. My dad isn't the type of person to troll, and I sure didn't put it there, plus the server that we are playing on is LAN based only. If someone can shed light on this weird phenomenon, it would be much appreciated.
