nope...took about 30 minutes before the coffer respawned today in garlaige. got there 5 minutes after the group ahead of us opened the coffer behind banishing gate 2. stayed there for about 20 minutes, no coffer spawns...went to gate 3, waited 10 minutes. no coffer spawns. went back to gate 2, coffer spawn!
