I think you encountered something that might happen with computers and programs. Unlike real life, everything here is basically a machine - man-made and thus with errors. Heck, my last blue screen was random and never happened in years.



Especially when it looks like everything works fine but in fact it's just an "illustion" on your side. I had one recent death in the Aether...bla bla...laboratory where I Displaced myself out of the boss AoE first and was the only one who got hit and died.
 I might have had a tiny, rare lag spike and the engine kept repeating the input (casting bar going up the same speed, my mates doing their attacks as before) on my screen while in real I was too late. It was not notable to me so I was baffled, but I a assumed a tiny cog in the huge machinery of online real-time video gaming was stuck for 2 seconds and that cost me my Lalalife..


I assume you have made it meanwhile, so it was a one-time thing.
