Last night, my Epic Bio-neural console had been replaced with something crappy. Wut?! Fortunately, I found it back in my bank (where it decidedly shouldn't have been).
I figured that was just a fluke, but today I noticed my (also Epic) Lukari armor, that I'm wearing, had been also been substituted for a blue Nah'kuhl one (not 'kuhl' at all, actually). I was ready to rain fire and fury on Cryptic, the likes of which this world has never seen; but, it too appeared to have been switched with an item in my bank.
My guess is that the new Filter system they added, had a few undesireable side-effects. So, caveat emptor! And should this have happened to others too, check your bank first before filing a ticket.
