Here are the details:

Single Island Challenge:
  • The objective is to reach max level (65) and to have ALL gear items and upgrades

  • A speedrun time counter will be shown on the bottom right part of the screen

  • Once the challenge is completed, the game ends and the time to completion is displayed along with the global leaderboards

  • Removed Buy Land button from the menu. Bridges and Landfill will be disabled

  • Initial land is slightly bigger (14x14 instead of 12x12)

  • Removed spawning restrictions (All Artifacts will drop on the starting biome, enemies will start spawning as normal, animals will also spawn as normal)

  • Artifacts will spawn on Markets and Slot Machines (I think they technically already do for Slot Machines, but I am not 100% sure)

  • At night, Skeletons and Demons may spawn (to add difficulty and reduce the grind for Bones and Demon Horns. On this update there is also a new craftable item called "Bed" that lets you sleep to skip nights in case you wish for an easier version of the challenge)

  • Removed Colonist buff from Shrines

Uhmm, interesting sounds like some things may be bugged then. I will take a look!
