My nickname does not match my wechall username....  Go to the IRC: Duckhunt challenge

When I started this challenge, my IRC nick was BusyR, while my WeChall user is just lowercase: busyr.

I overlooked the statement "Your nickname should match your wechall username", but ......

Upon reaching level 5, I tried the CheckAPI button, which gives an error:
API Result From https://irc.wechall.net/duck_hunt/level.php?username=busyr:
{"error":3,"level":-1}

Running the API manually with capitalized user shows the correct level (but does not mark the challenge as solved)
https://irc.wechall.net/duck_hunt/level.php?username=BusyR
{"error":0,"level":7}

I renamed my IRC user to lowercase, but that does not restart the challenge, nor solves the API issue...
Both "!duckstats busyr" and "!duckstats BusyR" give the same result within IRC, so I guess usernames in IRC or at least within #duckhunt are case-insensitive, but usernames in WeChall are case-sensitive...

So, my question is: can you
- fix the challenge API to that it's case-insensitive?
- or delete my duckhunt profile, so I can restart the challenge?
- or just mark the challenge as solved?

Thank you!
BusyR

Marked you as solved manually, we should probably fix the API tho.

Fixed the API manually, someone should keep a copy of these files.
