Bug: "Challenge [22]: Required item missing, unable to complete."

Description: With 10 trap doors in my hand or inventory, challenge can not be completed and give the error mentioned above.

Unable to complete: Challenge 24/28 cant be completed cause of the lack of redstone, cant make 10 redstone torches or a note block without it. Plz replace them with something use full or remove them from the list.

Dunno if this last one is a bug or not, but challenge list 6 is empty no challenges listed.

Hope this helps.
