Steps:
1. I was aggroed by a shelfscale sahagin and shelfpine sahagin
2. I was running towards the npc Fyuu and had clicked on him to target him.
3. I started to make the trade to Fyuu of the Whitecap Clams for the quest "Violence of the Clam".
3. At the same time shelfpine sahagin shoots my character with Water Cannon attack and my character become permanently locked to the npc Fyuu. I was unable to remove the courser off Fyuu and remained locked to him. Nor was I able to talk to the npc Fyuu.
4. The Whitecap clams were not traded and the quest remain opened.
5. Restarting the game was the only way to fix it.
6. I was able to repeat this glitch 2 times.
7. The second time no trade was started and still got locked.
