sk_soundingRocketChute does not slow down probe core

[CCBrailov]

I was running SkyhawkKerbalism as part of a huge modpack, and had no problems with the Osiris chute, but all of a sudden it stopped working. Since then, I've done a completely fresh install with the absolute bare minimum mods (just SkyhawkKerbalism and all its dependencies), and the Osiris chute simply doesn't slow down the core. It only drops to about 80-100 m/s.

Update: Can now confirm it's definitely SkyhawkKerablism causing the issue. No idea how or why it worked before, but now if I use a completely minimal mod loadout, the BDB small parachute works until I add Skyhawk, and then it (and the Osiris chute) stops working.
