Weird forest entrance north of Azureus? (late-ish game spoilers)

[TwoFaceTony]

When I got the airship, I was flying exploring the world and I found what looked like an entrance to a forest with some mushrooms around it. However, when I landed next to it, the entrance disappeared. I tried accessing it both on foot and in the airship but couldn't seem to get into it. As I mentioned, it's almost directly north of Azureus and in the middle of the continent vertically.
I figured there would be some key item I needed or quest to start before I could access it, however I not feel like I'm at the end of the game (I have access to the teleporter to the other planet), and I've still found nothing that seems to give me access to it. Is there something I'm missing here? I've been curious about it since I saw it.

if yes then it's just the entrance to the post-game DLC area, my guess is that it's a visual glitch, or might be intentional before you finish the game if that's the case

That looks like the right one, thanks for the info.
If it IS a visual glitch, I personally feel like it should remain visible in the air. Perhaps a message could be added when you interact with it stating something about the Glitch's power preventing entry. It would add some intrigue, and could plant a seed for people to look into it after beating the game.
Of course, if the game directs you there directly after beating the game, maybe it could be made invisible from the air again.

Sorry about the confusion TwoFaceTony! Dog_Guarada is spot on - that's the entrance to the Free DLC dungeon which is only meant to appear after beating the game.

Thank you very much for letting me know about this bug - I feel really silly for missing this (it's literally just one extra tick-box I missed) XD But it'll be fixed up in the next patch :D
