I'm not aware of any current issues with the system. Though the afk reporting system could have been used you seem to indicate that you were actively healing so I can't see why the initial debuff was not removed.
I can only recommend that if you experience an issue like this again, Pherox, please try and recall as much information as you can regarding what happened and post in our Bug Report forum.
From there our Quality Assurance Department can take the information you supply and try and reproduce what happened and hopefully figure out the cause.
