A while ago, while uploading post #459583 by hebimei_masayoshi, I was surprised to find that Find Artist wasn't working, which turned out to be because there wasn't any Artist entry. This was pretty weird since there was one before, I'm the one who made it. I just re-made it and forgot about it, but now I went to check on all the other images, I've found that all the source URLs in them were corrupted so that they couldn't lead to the Pixiv page.
Apprently "Ere" vandalized all the tags, urls and I'm guessing deleted the artist entry for whatever reason, I just hadn't realized since Hillside Moose fixed all the tag vandalism, though he didn't pick up the less visible damage.
