Today Newgrounds somehow got all the 2023 art (and posibly other stuff) fucked up. Searched trough newgrounds and encounter this in one of the comments.
So, if you had the same problem, say thanks to umesatro.
there's the post from where I got it.
There's some BBS from other guys who are talknig about this bug and aparently it's getting fixed.
EDIT: ALSO, I JUST CHECKED OUT, AND UMESATRO THEMSELF DID A POST ABOUT IT. Check him out.
