link steam account wont work?

it says i linked my account but i still se that 10 sg offer for linking my acount did i linked my acount? did i received the sg? is there a way to remove that from task list?

Every single SG you acquire is logged in the notifications section (including the information about what did you get it for): https://gamehag.com/notifications
This is the surest way of verifying whether a task/activity worked or not.
Just note that not all tasks grant you SG straight away, although linking your steam account should.

i did that task 3 weeks ago i cant find it now. Is there a chance this could be a glitch?

Could be. If you can still see the task, you can try disconnecting your steam account (in gamehag settings) and then doing the task again.

Happened to me. Just message Misty in the help tab and provide screenshots to prove you linked the account. They will add the points manually.
