"Lucky" me.
I found planet with three potential skimmer POIs.
The first one had some useless data.
I tried relogging - no luck after relog POI was purged from any loot, as expected, data port included.
Now is the interesting part - I jumped to SC and fles a few Mm to another POI, landed, tried to scan the port... empty.
Checked other loot - nope.
Apparently there is one part of EDO that is being contantly improved - protection against relog "exploit".
It seems like they have "nuked" it though, purging loot from all POIs from specific planet after relog is "a bit" of overkill.
Give them time, they're learning and attempting a clean-room development of video game creation. It's hard to find that many people who have never played games before ...but somehow Fdev persevered.
