Ah yes, I expected an answer like this.
Here I was talking about the same issue, caused by something else (Worldedit)
But as the same issue appears by only placing those monorails, not using Worldedit-> Worldedit is not the issue.
Anyways, excuse me for not being a pro at creating issue threads, but I'm not sure why you consider my video as "useless".
It shows exactly what happened, cause a bare description of the issue could be confused with a different issue, so I wouldn't say the video is useless.
Okay, I edited my post. ๐
To be honest, I was hoping that someone already experienced this kind of issue since it's not the first time this issue appeared. I thought it's something "common"
Thank you for the fast reply.
