Abandoned ship systems disappeared?

[PvK]

I've only got to sector 16 so far, only recently got a hand scanner, which I might not always bring, preferring a terrain device on appropriate planets, or an oxygen device for caves.

So far at these lower levels anyway, I find there are fairly often cases when I might otherwise choose to return to the ship or ascend or descend before exploring an entire planet or cave level, because I want to swap away party equipment, or I'm running low on air.

In space too, I may often want to dock or warp before exploring an entire sector.

So I'm just saying that this is now a competing consideration why I might think to avoid doing those things.
