this one is reachable after a side quest but i acually found an intel one that was unreachable. It sat on a table that was next to a wall and it was so far in on the table that you couldnt reach it.
Looked like the table had spawned in the wrong direction or something
"Nope, done it yesterday. I think those two are locked up behind a side quest called "Horn of Plenty". They are reachable, 100%."
Unfortunately this is not true. I went for then during this side mission and after, in bot TU 2.0.0 and 2.1.0 and nothing changed, the bug remains the same.
