Strange Forge Glitches?

Last night I was messing around in Forge with my friend and I thought it would be funny to create a flying weaponized whale. I’d made several welds already so I know how to do it. Regardless, when I set the physics to normal and went to get in. It spiraled out of control for several minutes until I could delete it.
Check out the clip in my content browser if you want, it’s the most recent video. I have no idea what I did wrong or if it’s just a glitch…

From what I’d seen, Lots of welds and scripts tend to glitch the game quite a bit. I’m not to good at forge so I can’t tell you how to fix it.
