We now have an updated version of the Sculpted Demon Army Wings. This version includes permanent fold and a new HUD. Fixed a few texture problems from the fold to open position. Probably some other things but I can't remember. *edit* Scripter says the wings are running Mono now.
If you own these wings, the update is free. You should get an inworld notice, but given SL borkage today, who knows. Go to the store, the upgrade sign is right by the landing point.
