Obviously number one on the list is griefing, but after that there is a lot which lacks consideration for other players Sand Snatching Random Route-taking Lazy Lumberjacks Dastardly Death-traps (at least this one wasn't too deep but I've come across many that go to bedrock or close enough to lava to lose items) Farming Failures Creeper catastrophes Purposeless Poles Architectural Eye-sores What's your pet peeve(s). What did I miss?
I'd like to say "all of the above". Though, if I have to choose 1 option, probably the fact that the landscape is in ruins, so much, that it feels like I'm going up and down mountains that shouldn't be there... :S
Don't forget the lava taken from /nether. In ugly patches of flowing lava.... bleh.... Or random mining tunnels in the wild that just lead to confusion...
I had forgotten about that until you just brought it up. Oh boy, but to be honest, I've continued some of those "random tunnels" and I happened to find some really nice cave systems~ However, I'm fairly certain that if I explored those caves long enough, I'd find that they were already connected to a naturally-generated cave... :\
xD Wild c on 8 has a maze of tunnels.... again, really amazing for enraged bunny hunting but really bad for surface level bunny hunting.... I've spent an hour trying to backtrack in those xD Such a pain.... No useful caves other than "LAVA" moments.... as far as I know, at least..
That dirt pole was most likely someone taking off on an elytra.. And that dirt eye sore if I'm looking at the right eye sore use to villager breeder back in the day... And honestly who can jump high enough to chop that last log... #TopLogsHappen
Chop starting 1 block off the ground, hop on the log on the ground, chop as high as you can reach. Place something under you if need be, get every log... Easy... (sorry if that came out with attitude, sir, as attitude is not intended)
