Necrotic Traversal - why don't it work for me :'(

I just tried using this on corpses in PvP and it wouldn't work. I kept casting as soon as someone died and it would cast then when it's finished casting it says "Invalid Spell Target". At first I thought it might be another Necro using the corpses but it's not because I can see they aren't used (go black when used). It's also definately not corpses getting rezzed either because they are still there after I fail to cast. I've also tried it from different ranges.

I just don't understand

It doesn't work for me in the Arenas.

Once again us necros are left in the lurch!

Strange, I'm sure I used it in Droknars but ages ago...
Report it to Anet and use Putrid till it's fixed guys, no great loss

Last I heard, it didn't work on player corpses in pvp.

This bug was fixed in the June 29th patch. Looks like it may have snuck back in.
