The bright version of this area accessible from the top-left wisp no longer has the hole leading to the School in version 0.105f patch 1. Strangely enough, where the hole should be is a cloud tile that is impassible and cannot be interacted with. This is pretty weird so I won't edit this in unless someone can confirm it. It'll probably be patched soon if I had to guess.
Yeah, the same thing happens in the sephia version, although i did notice something strange; when looking at the map on RPG maker 2003, I could only find the event that makes that hole teleport you to the School, never the one that takes you to Neon Candle World. It does, however, make me wonder if there's supposed to be a hole there in the sephia version that just doesn't appear, and if so, which world it would take the player to.
They're all the same event, defined by changing the value of var0003 upon entering the area from each of its different connections. There's actually a third possible location for it to take you, which is geometry world, but I'm not going out of my way to figure out where you can access it from right now.
Well, then I guess I still need to learn how to use RPG Maker.
Although, considering Geometry World is a nexus location, I doubt anyone would be interested to know how to activate an event that essentially just puts you back where you originally started, especially if it's similar to the connection to the School which just dumps you in some random location, and that's that, there's no way back.
Just how many versions of this one world are there, anyways? I thought the two accessible from Cloud Floor would be enough until someone discovered a third one, and now I just have no clue. It's not like RPG Maker is gonna give us much of an indication (Or at least, not before I figure out how to use it)
