How do I recover stage separated jettison?

[Mastikator]

"Kickback" Solid fuel booster description says it's designed to be recovered after jettison.

When I put it on my rocket, put 4 radial parachutes on it (that should be enough, right?), launch my rocket. I see that the Kickback SFB isn't there anymore and hasn't been autorecovered either, it just vanished. And I can't exactly keep my camera on the jettison while I am flying a rocket.

I want to recover the SFB, like it says I am supposed to do.

What do I need to do to make jettisoned parts not automatically vanish? The kickback is too expensive to just go to waste.

Use a mod like Stage Recovery. The description is just useless fluff text really.

The game has a 22km physics range. It used to be 2.5km.

What this means is that, anything outside this range will not get loaded and anything not loaded that is flying in the atmosphere is deleted.

The only way to fix this is indeed using mods to recover each stage.

(beware you need to add chute and/or probes to each)

Didn't they tell that these distances are moddable? Has anyone found out how to mod them yet? At least there are no config values for them.

^-- This, however Stage Recovery is currently not working and the modder has asked for a couple days to figure out what is going on. It is likely the recent hotfix Squad launched changed something the mod depended on.
