Difficult mode of the instance in which you found this issue: World issue
Complete description of your issue (do not forget to specify the issue, all conditions for making the issue to happen, and if the issue is related to a phase, specify the phase in which you found this issue):
If you fish up the item 'Stunned, Angry Shark' and use it within the 1min timer, it should spawn a shark that can be killed for a rare legion fish required for 'Bigger Fish to Fry' achievment. The shark should be called 'landlocked shark' at elast if used on land and drop 'Seabottom squids'
On sylvanas it is not spawning a shark but an untargetable infernal instead, it stays present for a few minutes and then vanished without giving the player a chance to obtain the rare fish.
If the Stunned, Angry Shark is used in water or on land it doesnt make a difference, i tried it with different sharks in different locations (suramar, aszuna coast).
Steps for reproducing the issue: If you fish up 'Stunned, Angry Shark', use it before the 1min timer runs out and watch the infernal.
Likewise the bait http://www.wowhead.com/item=133724 does not spawn http://www.wowhead.com/npc=102374 necessary for catching http://www.wowhead.com/item=133742
Yes i noticed this as well with the following items.
Tested it few days ago, the achievment is completable and this is no longer bugged. Considder this resolved.
