OLD POST, but here in 2023, I'm doing the same thing, running around planetary station after another, trying to find landmines. INARA says they have it, they don't. Finally, after five planet visits, I "enter hangar" because I'm taking a break, usually I do everything on the surface. Low and behold, after commodities markets says no landmines, enter hangar, and they show up, as INARA reports. ENTER HANGAR, guess they don't like doing some business above ground.
