Lua Caches in Impossible Places

[Yamana]

As I was farming lua exterminate missions for the 3 caches, I found there was (too often) cases where the third cache just isn't around. Icons would appear off the map sometimes, or not at all, but one particularly infuriating cache was one we could hear and see on the map, but could not reach due to boundary issues (or it's in a wall).

As a follow up, in a later mission we found out if the globe detaches it opens up a hole in the wall, but in our mission the globe never detached.
