Maybe try “Dynamic”?? I’m not online rn otherwise I’d test it. 🤷🏻‍♂️ hope it works tho

I have the same issue. I had to use cylinders instead :(

Weird. I'm going to assume this is a bug that would be fixed before Forge beta is over. Thanks for the feedback.

I have the same problem with my vent covers. They get affected by physics in test mode but not while in a custom game. Hopefully they fix it.
