So, I've built an elevator and whenever I try to activate it it turns invisible... Also when I try to stand on it I fall through yet I can't go back up through it

Can you send screenshots of the elevator you are trying to make?

Welp, it looks like I won't be getting a photo... They didn't backup the world before they reset. I'll try to reproduce it

I also have trouble with my elevators going invisible + I fall through.
It happens when I come out of the mining dimension via Aroma1997 Dimensional Worlds near the elevator in the Regular world.
Appears to be 100% repro so far.
The Elevator controls also act as if there is no elevator placed.
Also other players on the server COULD see the elevator & use it if they went to the elevator by normal means (not going through the Aroma1997 dimensional world) and I could watch them use it while I could not use it, nor see it.

Falling through should now be fixed.

There is one case of invisible elevators caused by a minecraft bug that I can't fix without asm, it is where elevators in certain locations go invisible from certain view angles
