attack log missing?

[korea69]

I checked my account this morning, last time I checked was last night, I see that my naq is extremely low, I look at my armory, I was attacked, repaired the damage, went to attack log to see who did it, nothing was there, so it didn't even record a attack??

Maybe the person ascended, if so all logs of his gets wiped from existence, no trace.
