A week ago I posted a thread about a leak that doesn't existed, that could only be fixed by copying the hole map into a new file. I started a new map but now the same Problem appears again. What can I do to fix this?

Did the problem apper right as you copied it? If yes, the leak probably really exists and you should check it better. If no, I'm unfortunately no help here.

Leaks don't just spontaneously appear. You must've moved some brushwork around and created a hole that way.

Unless you mean you're getting FindPortalSide errors, which can happen even without a leak (though it's rare), and is usually caused by excessively complicated world brushes giving vbsp a hard time. Fly through your map and convert any particularly complex geometry into func_detail, then re-compile.

Anyway, it'd be super duper helpful if you could paste the entire compile log here (not just the error in question).

Did you use an areaportal?
No, I didn't use them

Edit: I fixed it, the problem was as Muddy said the "FindPortalSide error" that was caused my two displacments overlapping each other!
