you had a dot, coth acted like fd.. Your agro was cleared and your dot will not cause agro ON THE DOTTED MOB, but it DOES agro any mobs around it when a tic hits... Its as if you casted on the mob but the mob itself ignores the dot but if anything is around it, that will re agro.

now that I see ur screens I can guess that is what happens as you will note the dotted mob didn't come back, just the ones that where around it.
