Hey @ Thanks for the prompt response. Do I have to use Steam for multiplayer in ATBTT? Or is there an easier way to get it working? Also I’m having trouble with the hover tile marker and spline. They only appear on some of the tiles seemingly at random. They also tend to lag a bit. I’m not sure what is the cause of this. I have made a lot of changes to the toolkit but I haven’t been able to find a solution for this. Any idea how to fix this?
