(in response to your message) In your update to Ember model in 5/21/19 you make particles properly disappear at death, so this might have something to do with Rain of Fire. Also it could be a looping animation, like death. As far as i know imports do not leak, so it could be an issue with the rain of fire spell after the updates, but that is improbable. Anyway, keep up the awesome work you are doing.
