I never left, I'm just sooper spoopy and lurk forever in the dark.
Also, in case anyone is wondering, this was a test for the file upload limits. It would appear someone, sometime, fucked around with the previously set limits from the admin panel and this resulted in them glitching out like last time many hundreds of moons ago (I reckon some 5 or 6 years, maybe more) and so now the PHP limitation applies instead, enforcing a 2 MB limit on all attachments and node files. No way to fix this except through the website configs. Soz, someone find the website owner/hoster.
