[Skyblock] /headgrabber glitch [ FIXED ]

Sorry for the trouble, I figured out that apparently 1.7.5 was just being buggy and the Sky Block server wasn't. Sorry!

Username: ReecyNightshadow
In which minigame/server does the bug occur: Skyblock 1 (I'm also going to assume 2 and 3)
Detailed description of bug: Okay, when the skyblock server was back up somewhere around the 25th-26th of May I logged on, went into my shop that I have and all I saw was ( default steve heads. I assumed the heads needed to load and it may be a few minutes but they never did, I also logged on later today ( 5/27/14 ) any they are still default steve heads. Any player head I use /headgrabber on end up being a default head and the name is just labeled as "head" instead of any player username. Glitch? Or were heads removed from skyblock? Screenshots below.
