Bleagh. It seems at some point recently the wiki was no longer functional. And seeing as the plugin hasn’t been updated in (checks notes) 7 YEARS lol, I don’t think that’s too unusual.
Anyway, I managed to fix it by resetting the plugin url scheme, no idea why that worked but it did.
But for the future, I should probably move the wiki someplace more robust. I made a page on fandom. I think anyone can make entries and edit it.
I copied a few pages over just to test. I don’t have the time or energy to do this, but if people were actually interested in salvaging it before the next DOOM EVENT, then that’d be pretty cool.
