Well I had a level made in 1.16 and i edited in 1.17 and a couple of objects fall through the floor.
Now I built a new level and it still happens. I have it dynamic and mobile so you can right click and move it. If you drop it, it goes right through the floor even in the completely new level. What's the deal? Tried everything, that's why I made a new level just to test it.
Edit: OK, I have reinstalled, used cleaner, built a new test level with different floors and the pad falls right through on the first or second drop. I thought it was the original level, but....
It worked in 1.16, now not. I also tried other entites from the scifi/items and they do it too. Anyone got any ideas? Please
