Hello! I've been told that the blue "light tube" entity/object is related to a certain event (as mentioned by the wiki and some friends), however it has been appearing every single night without any other interaction. My run is on day 23 and I have not seen a single entity other than a (spoilers) ->                    cloaked ariral at the tree house and the light tube. I'm beginning to wonder if my run is bugged, or if this is just an intentional part of gameplay and I've been tactically misled by friends trying not to spoil the fun. 

the light tube spawning repeatedly is definitely a bug, but for the most part, you won't actually see much early-mid game, and it is very easy to straight up miss events- adds to the replayability of the game at least, so you don't have to feel bad about restarting after updates ;)
If you've gotten gifts of sushi and croissants recently then story events are still happening

I haven't either. I'm on day 21 and the only "scary" things I saw are Ariral pranks such as the alien catapult. After reading the changelog I expected the update to be packed with scares and THREATS, but just... Nothing happens! Other than Dr.Kel frustratingly refusing to go to sleep even if there's nothing nearby.

I thought it was just me getting immune to everything weird in this game.
