Okay so Heart of the Isles just before the giants and stairway down to Bunny (on the left as you enter is another door leading across a bridge of lava), I was alone and shifted in Animal Form. No Allies of any kind, PC/NPC and not partied across areas. Just killed some salamanders and was headed out to avoid the fire giants. I walked back through the doorway that leads to the stair room and stepped over the corpse I had looted before going past.
The trap set off and fried me instantly, whats odd is I could swear that trap was not there as I walked over or very close to that point before. It may have been because the traps set funny sometimes but it seemed like it, and a few others, spawned in at some point while I was killing off the last of the salamanders.

When I returned to the area to claim my gear back I tripped another before I made it out I believe, on the area above; when I spawned in though I also noticed the spawns re-appeared when I went and stood by the entrance to the area I died in in the hopes of equipping safetly. Not sure if its relevent but added it anyway, beyond that I dunno what else to say really.
