It's very sad to see you go on such short notice. It's very unfortunate that this has to happen right before the party, too =( I'm sure there's a way to fix your dilemma though. You can post about your issues and bugs here (https://feral-heart.com/smf/index.php?board=24.0) in the Help boards if you want to attempt fixing this issue. First I would look for any extra particle files with _0, _1 ext. in your particles folder. FeralHeart> media> particles.
But if you wish to leave, then I wish you well! Stay safe out there and take care~
