These achievements are still broken and the dev is an absolute scumbag for deleting let alone banning criticism. This game was a mess on all platforms. I played a ton of the playstation port and this one over remote play together and it's been a bugfest from the very launch.
Weird, comb shaped error islands got generated, multiplayer consistently broke and or lost audio, you'd start spawning entirely empty levels of just generated landmass and no props or npcs.

It speaks novels about Nap's character as well as the studio's for leaving him in charge of the communities. I'd rather just emulate and remote-play the original than support devs like this.

Yeah these achievements are definitely bugged, I got several for things I didn't do. They just popped up randomly.
This whole game is incredibly bugged. Every time I join an online game, my save files from my single player games get deleted. There's a whole bunch of other issues I've encountered that I won't bother getting into
