Pet summon failure

[zecra0]

On my elementalist and my lich, when attempting to summon a pet, I got the text dialogue and used the MP/AP, but no pet was summoned. 2/3 of my Ghouls were summoned, the third lost to the void. On my Ele, I summoned a gnome 7 times, with one failing early, and the Juggernaut I attempted to summon failed.

Most likely you hit the summoning on pet tick that fails it.

This used to be a rather rare event, but the recent server lag has made this much more common.

Is there any way to add a check at the end of the summon to make sure the pet actually appeared?
