Summoned by non summoning mobs
 

I was summoned today by either a centaur in SK or by my pet. One second I was a few feet away, the next I was right where my pet was getting beat on. There was no red summon text, it just happened.

This also apparently happened to another pet caster in the zone earlier in the day.

havent had this happen on my mage or necro or chanter and i play in SK daily. Not saying it didn't. Will post if it does.

Sounds to me like you just lagged and warped.
