This means you have not installed the teleporters correctly. Most likely you chose the wrong square. Or perhaps your server simply does not have time to load the map, try changing the delays in the sandbox parameters.

Can't see the drain cover.

And Edit Teleport is not Working...Just Keep Error

Hi. This is most likely an incompatibility with some modification. Try disabling all mods and make sure the current modification is stable. There is a huge chance that there is a modification that brazenly changes the standard UI.

got multiple errors popping up especially when i try and put paid gloomy ports out

@Yekip. There can be no mistake.
You probably have a modification that changes the default behavior of the getBottom() function - It is static in the game and is the code from the developers.
I recommend removing modifications related to the UI extension, for example SimpleUI and I think the problem will go away.
