Need help with Areaportals

[Yumbos]

I was doing a Halloween version of Process, but when I changed some parts of the map all the Areaportals in the map seemed to have the same error; Brush X: areaportal brush doesn't touch two areas.

The thing is, I didn't even touch once the areaportals, I have tried everything to fix them all, but it seems nothing I do works.

(If anyone needs the log. file let me know and I'll send it to you)

PS: All the images below are examples of some leaked Areaportals, but as I said before, every individual areaportal is leaked apparently (sorry for bad grammar lol)

It looks like there ought to be a skybox brush here, have you removed one?

Areaportals will leak if there's any path from one side to the other, so if you've moved some geometry and created an air gap, then you've broken that area portal

For making areaportals, make sure you turn off all auto visgroups except for world geometry. Func details/brushes, clips, and displacements can't seal portals so you don't even wanna see those when making them (The only ones you want visible are World geometry and sky).

Just make sure to turn your visgroups back on when you compile though lol
