I tried the code, everything works fine but the players are always glitching in the air above their head.
(Teleported +0,1 y and back)
This is not visible for other players but a little bit annoying.
The second issue: If you are in a vehicle, you'll glitch out of it.

All this happens in a regular schedule, every second.

PS: These issues do not exist in the latest/last official release of the plugin.
