We have the problem, does the elevator speed up to 4x ,we clipping through the elevator an fall down into the death. The Post 6month ago that was fixxed is not possible by us, i hope u can help, that we can fix it together.

Thanks for reaching out. Do you know if the players are standing near a wall when they this issue happens? The way FP implemented the clip checks is that if the player is clipping into anything, it will unparent them from the elevator. The issue 6 months ago was that they would often be clipping into the elevator itself while moving fast, so the clip checks would think they were exploiting and dump them. To resolve, I made the clipping checks a little bit smarter, so that certain entities would be exempt for clipping, such as the elevator itself. However, I'm aware that if the player stands near a wall or something else while the elevator moves, the clipping check may still think they are exploiting.

Also, somebody else recently said the same thing as you, and they said they were using the latest version of the plugin, but when I asked them to check, it turns out they were still using an older version. When they updated, the issue was resolved. Please prove that you are using the latest version by posting a screenshot of the output of running o.reload BetterElevators.

Thank you for confirming you are using the latest version of the plugin.

Thank you as well for confirming that the issue happens more frequently when standing near a wall. That confirms that the existing mitigation in the plugin is at least working some of the time.

Can you clarify, how often does the issue happen when the player is standing in the middle of the elevator? As a conditional follow-up question, if it isn't very often or if not at all, do you think it is feasible to educate your players to avoid standing near the edges of the elevator?

As far as what the plugin could do, it is likely possible to further improve the clipping logic to avoid falsely dropping players through the elevator, but extreme care must be taken to ensure it does not re-enable vanilla exploits. I am not very familiar with the exploits or how to reproduce them, so any potential improvements to the plugin to mitigate this issue will likely take some time or be low priority amongst my other projects.

If you want to help me move this issue to resolution, you can start by researching the old clipping exploits and learning how to reproduce them. I can then share a modified version of the plugin that removes the clipping checks, so that you can verify the clipping exploits can be performed. Once we can baseline how to perform the exploits, we can attempt several improvements to fix players falling through, and test the exploits again to verify they cannot be performed using the custom clipping logic.

Thank you very much for taking on the problem. 

I will pay attention to which position exactly the clipping continues to occur and let you know where it occurs more frequently. 

It will take a few days before I can give you an answer regarding the positions.

Hello, we found out that the elevator clipping problem only occurs when using the garage doors instead of walls. 
With frames with garage doors, you fall through the elevator 75% of the time, which is almost impossible with normal walls. 
Maybe you should write that with the plugin that you should rather use the walls so that the problem does not occur. 
We apologize for the inconvenience we have caused you. Thank you anyway for the time you took.

Good find! I tested this and found the same issue. If the garage door is positioned so that it sticks into the elevator shaft, it reduces the area that players can safely stand. In vanilla, the elevator is slow enough that the player is pushed to the side. While going higher pseed, the player is pushed through the floor.

I will consider updating the plugin to allow clipping into certain objects such as garage doors.
