The Jem'Hadar armor visuals aren't showing up for me at all. I got the set the other day. I don't know if this is a bug or if it just hasn't been made available for KDF yet. The patch notes didn't specify if it was fed only or not.
In unrelated news, the omega store registration seems to work.
I just bought the Undine armor and it has no tailor options either. And no enable visuals option.
All I get for my ticket is a canned response directing me to the forums and an empty wiki page.
I'm having the same problem Dyson Joint Command Ground set, and I completed the set as of yesterday.
I had the Personal Shield for a few months, got the armor on Friday, and the weapon on Saturday, but I can't make them visible in either the Status screen or the Tailor. It appears whatever recent update we have has temporarily caused the visuals to mess up. Heck, every now and then parts of the maps I go on despawn graphically, and take a few seconds to come back. It's annoying when you walk into an invisible wall.
