There is no MC crash but when I try to open a world telepad version 1.7.10 Full Release 3.1 Minecraft itself load all mods fine but when I try to load a world it fails to load, I have tried multiple versions and it ends up the same result with the error text "Connection Lost. A fatal error has occurred, this connection is terminated."

I get the same error, on the curseforge page it says something about needing another version of bookshelf, but idk for sure
