Yup, confirmed... BuffBars hasn't seen an update yet so until then, nobody should be using it unless they don't mind frequent client crashes.
I'm currently running Bootstrap, Baruk (I LOVE IT!!), LIP, Compendium, AltTracker, MouseCursorHA, LotroPad and probably one or two more that I'm forgetting about - all without a single hitch
I miss BuffBars though
