The Moonlit Caves was a dungeon that was actually bit different compared to the other dungeons Ark had been to before. Unlike a dungeon with different levels, the Moonlit Caves was essentially a cave system, with each cave having different levels of difficulty. It wasn't like you needed to beat a certain level to be able to advance to the next one or something. If you were strong enough, you could just go straight into the hardest cave without even looking back.
Hopefully, the schedule should be back on track next week, but I can't say I promise anything since I'm bad at keeping promises when it comes to my upload schedule.
