PSA: Fishing with Sharp appears to prevent two fishing-related achievements

There are two fishing achievements that are separate from the zone "Master Angler" achievements. My two friends and I spent multiple hours fishing in Wrothgar and Necrom today trying to complete these without any luck. After searching online, I found someone who mentioned that having Sharp out might prevent these achievements.

We tested this theory and after all of us put Sharp away, each of us managed to get the achievements within one or two pools in each zone. So there definitely appears to be an issue with Sharp.

Here are the two achievements in question:

Orsinium: Hooking Wrothgar's Biggest Catch
Catch the rare Crab-Slaughter-Crane fish found in Wrothgar.

Necrom: Pulled from the Depths
Encounter this rare and unusual fish in Apocrypha.
