I’m having an issue after I use Mark of Aquaos, and kill the mob that spawns, I’m unable to loot anything until the bubbles have gone and the water returns to normal. I cast my line, wait until the bobber bobs, then click on it, and nothing happens. I have tried flying away from the area then returning and trying again. I have relogged, but nothing works. I can’t loot from my line until the effect of the Mark of Aquaos has faded. Advice please? Thankyou so much. 
EDIT: Having zoned three times this issue has resolved itself. Please delete this post, it won’t let me do it myself. Thanks <3
