There have been a variety of issues reported here in the forums that we're told will be fixed in the first update for Archicad 25... but the date of release of that update has not been announced yet.
So... as is the advice with every new release anyway... go ahead and install it and learn the new features, but unless there is a compelling reason to do projects in it right away, wait for at least the first update/hotfix.
