[SOLVED] Annoying skybox bug I can't seem to fix

[The_SloVinator]

EDIT: THANKS TO NaZa FOR THE SOLUTION!

Turns out, I had to make a separate sector for the monster teleport tag.

==============

 

This has happened to me numerous times in the past & this time it started to slightly get under my skin because I have no clue how to fix this. (In the past, I changed the geometry because the bug wasn't as large as in this screenshot but it still took me a while to finally remove it. Honestly, I don't want to change anything here unless it's a last resort.)

I also have no clue why does this happen. I made this area about a week ago & it had nothing like this till today.

Nothing was moved & nothing changed here except I populated it with items & monsters.

 

This is running on gzdoom but this bug appears in DSDA as well, which is what this project is design for.

 

I'd like to thank you guys in advance for the help & tips.

Got the solution!

Are you using sky transfer? Sky transfer applies on tags.

Yea, I was using the sky transfer & now I understand what the issue was.
