Big bummer when I found that the Tethered Teleport enchant doesn't work with the teleporting in the Waystones mod. I would even hope for a config option to just have the Tethered Teleport feature turned on permanently, as servers that use any kind of teleport mechanics mean it's either entirely pointless to take pets with you or you have to ignore the whole teleport system unless you use the collar enchanting mechanic purely for Tethered Teleport.
