Well I know it isn't any dll files that are missing, because this would cauae FeralHeart to crash upon opening it.
It wouldn't be double particle copies, because it would've crashed upon opening FeralHeart.
Plus, also to add to what Bloo has added. If reseting the character doesn't work, then the server is just being weird again, but I haven't heard about it this month, so not likely. If you don't want to reset your character then you'll have to wait for the number to drop. However I'd recommend to reset it.
Just another fact, it is normzl to experience the 'FeralHeart.exe crashed' when going into maps sometimes.
