I know a lot of people for the past year or more have been having issues with this mod. Which really sucks because it was a great mod and I loved it a lot as Im sure you all did.
Im pleased to announce though that there is a more stable version that someone made (some time ago) that Ive used for several months now and its been stable and had far less issues and comes more feature packed! The below mod as well has more of a chance to receive an update in the future as well.

(You will need to uninstall the original version of greenfire before installing this one)
