Veteran and/or Item Shop Beacons have been changed by 18.7 such that they are an "instant" cast ... much like an emergency Meep. Consequently they were apparently caught up in the Pvp issues and now can not be used if you or your allies are in a fight.
Currently on Live they have a "longer" cast ... 30 seconds iirc and they do not check for if you are in combat.
Please put them back to as they are with 18.6. I.E Do Not change them with 18.7. An instant cast is useless if you can't use them while in combat. I/We would rather have a longer cast, but still be able to use beacons while in combat ... particularly when it is often a mob we are not actually fighting or a bunch of mobs someone trained to us. Keep in mind these are items your Veteran customers and/or Item Shop customers purchased.
