Hi there,
I have a problem with the acievements, where although I should have completed them, they do not give me the reward due. Can you guys help me out with this? I’d really like to get my reward! 
it’s been reported a few times here. the devs are aware of it but it’s not been pinpointed yet. I’m in the same boat. i only have my signup achievement and have beaten every level released so far.
It’s like these ones, right, where you aren’t getting 1, 5, and 20 levels complete achievements? https://github.com/codecombat/codecombat/issues/1780
Hope to find the bug on this one soon, but haven’t figured it out yet.
I am also getting this bug
