Hang Glider can't use in server .
But single player mode can use it .
I use kcauldron 1403 server .
It's happening since openblock 1.4.2 . I use openblock 1.4.3 , but this bug not be repaired.

Closing, since it looks like Bungee/Cauldron problem.

What do you mean by "can't use"? I can't reproduce this issue, hang glider deploys normally, even on server.

Sorry , I found it not beause of mod version and server. it might because of bungee . I found no bungee to link it can work , but on bungee it can't work .
