I've got this strange problem I ran into only since recently.
Usually, when I got a new or existing project and I run
composer install or
composer update, composer will automatically copy (map) the contents of
magento2-base to my project root. So
magento2-base/lib gets copied to
magento2-base/app/bootstrap.php gets copied to
/app/bootstrap.php and so on...
But for some reason composer is not doing this anymore. Does anyone has any clue on how this can happen? I'm experiencing this issue all of a sudden since last Friday.
