Note: all locations are random and can be repeated. Sometimes a search results in nothing, and there is a reset on each searched item of at least an hour. Another trick seems to be to zone out and back in. This will reset the searchable locations. Some locations to find searchable crates are:
( -34, 2, 41 ) /waypoint -34, 2, 41 in a crate next to the entry to the zone.
( -44, 1, -16 ) /waypoint -44, 1, -16 on the island next to Lukur.
( 3, 0, 13 ) /waypoint 3, 0, 13 in pile of crates in middle of the room immediately west of Lukur.
( 23, 0, 0 ) /waypoint 23, 0, 0 at the edge of the room immediately west of Lukur.
