Steps to reproduce:

1. Place a harvester
2. Use a yeta wrench (or similar) to point the harvester up or down
3. Give it power
4. Crash occurs.

First noticed in multiplayer (causes a server crash loop), managed to reproduce it every time in single player.

Damn, hadn't considered people rotating machines with tools. Thanks for the fix, will put out a new version when I get the chance 😁
