It's been quite literally years since I've used these, but are they not working currently or something? When I use Shadowland Safeguard I'm getting the 'You successfully bound x teamember(s) to this location.' message, said team members are getting the 'You were successfully bound to this location.' message and then when I target and cast Impel Shadowland Recall a few minutes later without my engi having moved anywhere (no disconnects, team member is still in SL etc), nothing happens. If I use the lower pair (Shadowland Anchor and Initiate Shadowland Recall), the same things happens. If I mix and match, again nothing happens.
So what gives?
