Maybe! I’m definitely not crossing that out as a possibility. However as this is a relatively early level set of maps with links to various other maps I feel like there’s still more to it. I can understand later areas in the game/development being more incomplete though, like missing items for recipes and so on.
We’ve been told elsewhere on the forums in the past that there are secrets still undiscovered, so I’m keeping an open/positive mind that it’s “functioning as intended”, as the support team like to cryptically put it.
