When I use teleport command such as teleporting to people, or warps such as /spawn - or even command blocks that teleport me to another place, my pets just completely disapeer until I disconnect and re-connect.

I think they should teleport to me after ANY teleport command, anything that teleports the player, should teleport the pet too - I looked through the config several times and tried adjusting different options which didn't work, what's weird is my friend came on my server and he teleported fine with his iron golem, not sure if it's just pet-related, but my creeper pet won't teleport with me however, please fix this - this is by far the best pet plugin I've used thus far.

See Dev Build 24 for inquiry into a solution to this issue.

on my server i dont have this issue, with #24 of echopet dev build.
