Please provide any additional information below.
When I warp on horseback, I find myself standing at the waypoint but without my horse. If I relog, My horse reappears.

I've been running HorseTools since since it's first release on a pre-existing server and this glitch only happened on rare occasion. I'm now rebuilding my server from scratch and on this new build it's happening about %90 of the time.

I have tested this with both player perms and '*' perm.

I am running bukkit 1.7.9-R0.2 beta, Essentials-2.13.1, PermissionsEx v1.22, CraftBook v3.8.9 as well as the usual worldguard, worldedit, etc. Essentials is handling warps. I have no other plugins that mettle with horses.
