Chutes opens instantly after staging

Question

Hey there :)

I've got the stage recovery mod installed and try to recover as many stages as possible for every launch. But I ran into a problem with stages in low atmosphere (~2000 - 10000m) because the chutes on my boosters try to open as soon as the stage is decoupled. The chutes are set to open "when safe", at 1500m altitude and it requires a pressure of min 0.5 but these settings are ignored and the chutes are destroyed due aerodynamic forces.

The chutes are in the same stage as the decouplers and usually displayed with a red background (not safe to open) when I want to decouple the booster stage. Unfortunatly, the chutes must be toggle together with the decouplers, otherwise they are destroyed (by hitting the ground) before 'stage recovery' can recover them.

Additional infos: KSP 1.4.3, stock chutes

Any ideas how to work around this problem? (except for probecores and using FMRS instead)

Try to increase the pressure needed for opening chutes. Chutes open as the rocket is rushing through the atmosphere and the pressure is higher. Worked around that one a couple of days ago.

Perfect, works like charm, thanks :)

Better yet @4x4cheesecake, put the chutes for the stages that will be recovered, higher up on the staging list.   Once the stage is fired off, SR doesn't really care if they have actually opened or not, it just assumes that since they will theoretically allow for a safe landing, they will.  And the chutes will disappear from the list when the stage is released.   

I don't know about stages that would land while still in physics range, but anything that gets staged that soon (on a rocket at least) may not be worth recovering, or even dealing with the added weight of chutes....

Usually, I put all my chutes at the very top of the staging list but like I've described in my OP, this strategie does not work with stages which are decoupled at low altitudes.They hit the ground before anything can be recovered.

It is still kinda strange, that the chutes ignore the "open when safe" option but not the settings for atmospheric pressure. Anyway, it is a way to work around and thats fine for me.
