Buggie despawns

[xAsherothx]

I have had an issue with my buggie de-spawning back to the nest. If I get too close to the cold region my character jumps off the buggie and it goes straight into the nest. I cant whistle to get it back. Also, when I was by the ominent facility level b10, by the statue, riding my buggie, my buggie went right back to the nest and I had to run all the way back to my base to retrieve him.
