Hey all, I took the liberty of checking out the coordinates listed in this thread, and to help folks narrow down the locations a bit, for where they wanna search at a given time I have made a list of the coordinates and put them in two categories: High Security Station and The Tomb.
High Security Station
-320,60
-1253,179
-606,746
-1149,1292
-704,153
-1217,1348
-702,153
-1153,250
The Tomb
-700,-1956
-734,-1774
-482,-1615
-437,-2178
-325,-2170
-159,-2015
50,-2052
169,-2095
-240,-2309
-381,-2484
The only problem I ran into with this, is that there was one set of coords that didn't seem to point to anywhere. The closest was High Security Station though. In the interest of completion, I am listing them here anyway. -158, 178
Edit 1: Removed one set of coordinates due to apparent mix-up. (-704, -1960) and fixed the text to be a little more consistent.
Edit 2: Removed another duplicate set of coordinates, and checked each of the spawn locations in The Tomb. (Found 2 cubes during! )
