You can't level in the meantime? Or are you one of those spacebar players who rushed through the game and is now complaining about lack of end-game?
I suspect it's the latter.
Obviously we are at 50 since we are doing hardmodes. You don't have to spacebar through everything to be at 50 by now if you've played a lot since the first day of early access. It's not that we can't do anything else, as much as it's the fact that a big part of the game, end-game dungeons is not even working. They are not glitchy or lack content, they are not present at all.
You should be happy, if everyone was as slow as you then you'd get to 50 and you would discover, with all the other fan-boys that come with the same ****** argument, that half the end-game content is unaccessable.
