So I woke up dead this morning with some helpful signs from Iya letting me know i had died and that my stuff was in the chest. Thanks Iya.
At first I don't know how i died but after finding my water flowing off the mountain and a dirt block inside my home and considering where I was facing I think I have the general idea.
1) Enderman was on my mountain and picked up one of the dirt blocks on the edge of my hemp farm
2) It started raining so Enderman teleported inside my facility
3) It saw me staring at it and attacked me until I died
At least that's what I'm piecing together judging by the evidence.
EDIT: Wait...2 other dirt blocks that I certainly didn't put there. I have everything flat. So the Enderman made more than one trip to my home. God dammit!
Don't forget the sign pointing to the dog. *nod nod*
Oh btw I killed myself on your elevator earlier. :B
Oh also I used your elevator. :V
