I am unable to bring up my skyblock challenges window in the gui.
This started after the challenges were taken down to be updated.
When I type /is and click the challenges button, the gui exits back to the game.
When I type /c, I get the message 'An internal error occurred while attempting to perform this command'.
I am able to use other /is commands and I can complete challenges using the '/c c' command, but since I cannot bring up the window I cannot see the different challenges and what the requirements are.
The error happens whether I'm playing using release 1.7.5 or the newest 1.7.9.
I was hoping it was connected to l33t_h4wk's challenge issue in thread http://meepcraft.com/threads/skyblock-master-challenges.22252/, but that was just posted as having been resolved.
