Nothing big, as far as I'm aware of, it's just the original bit.ly links for the dump and injection tools provided by OP weren't working since this morning (as documented on the forums) but the backup links Sopheroo mentioned:
Are working as an alternative. Ram Editor and LeafTools still work and everything I think. Just used LeafTools to unlock all PWPs without issue a couple days ago.
*Don't inject with the original bit.ly inject link for now since it seems like it caused cassriale's game to glitch with the dates and she lost a villager. I just tried some pretty big edits, including building moves and it seems like the lunarcookies links work fine. I haven't saved the game to apply the changes permanently but I'll do that sometime in the next few minutes.
EDIT: Made some typographic edits... Post was mad ugly.
