Hive Engine Script Updates

Script Status

Over the past week, I've had a chance to help out @lassecash with his new Hive Engine witness deployment. He was using my github script without luck and as I tested deploying it I found that I saw problems as well.

I finally had time earlier this morning to sit down, work through the code and find the new bugs to get it cleaned up and back to a 'working' state. Another huge update is that there's a new mongo backup that I'm pulling down that speeds up the deploy quite a bit.

Script Updates

So again, you can get this script at github but I'll also post it below. As always, let me know of any issues you run into and feel free to hit me up on Discord: blervin#9759
