CRAFTBOOK-3461 - Reported by Govindas

if I place a sign at the destination of the elevator, it says location is obstructed, I think this shouldn't happen for signs as the player can freely be inside them, it's also pretty annoying as I have to rebuild a whole giant elevator due to this. only happens since I updated to 1.13.2, it was working well on 1.12.2

happens on both wall signs(if it's at the 1st air block) and floor signs. tested with craftbook 3.10.1

Try the latest dev builds - there was a Spigot issue that caused this, and a workaround was added later.

the latest dev build was 25 days ago if I'm looking at the right place, I have already tried it earlier

This was fixed a while back by working around Spigot issue
