Seems like there is definitely an issue with Live Fennux running with you (when you attached a fennux to Avatar Center and it runs along-side your avatar.) I and others keep seeing “stack heap collision” with the script “Jump” every so often. It only happens when you are actively moving your avatar around while wearing the Fennux.
This issue showed up out of nowhere, and it’s not like we have updated the scripts inside the Fennux recently – so the issue literally showed up out of nowhere.
We are working on a solution for this – so please do not send any more support tickets about the issue, as it’s being handled as I typed this.
