CI4 upgrade from version 4.2.1 to 4.2.6

If you have the system folder in the root, it means you installed CI by manual.

No, I installed with composer, I had to copy the system folder to the root because the new version of the Paths.php file (which I replaced the old one) at line 28 reads:

PHP Code:

public $ systemDirectory = __DIR__. '/../../system'; 


In order to use the folder system in the vendor folder I have to put the old path back ... I'm confused

Is it an error in the file composer updated in the vendor folder?
