Its not a bug, i tried to change the task the first time i got it aswell, but since they are low lvl the task cant be changed. (A lot of ppl have already posted this prolly)
I thought of something with rug, but i dont know, btw its lvl 1 lol. would be nice if someone who knew could help. thx EDIT: Anagram: "Err Cure It" Answer: Recruiter (West Ardougne center) (looked it up :))
