Nadox run like any other, started with Vistrinda as I always do, fight went without a hitch, and in under 7 minutes or so, she dies. Except the corpse disappeared immediately upon death.
Tried /hidec all /hidec none.. tried zoning.. tried looking through the floor and up to the ceiling. /target and /assist Vistrinda provided no corpse.
Did nothing special or different. Did have 1 set of eggs pop corrupted on me because I was DPS burned alongside the first set of freed dragorn and brought her to 60% much quicker than I'm used to while fending off caretakers, but that's happened before.
First time I've ever had anything like this happen.. *shrug*
