According to the advertisement for 3.1 back in 2015 (http://www.swtor.com/gameupdates/conflict-on-rishi), Bloodhunt FP was supposed to drop the Illumination Probe Crate SH deco as a reward for doing it in HM. Currently, you only receive the Decorative Gear Arrangement for doing this FP in SM. There is no HM deco reward other than what's on the RNG loot table when you beat Shae Vizla, which in the last 20 times I've run this FP on HM, has exclusively been the Decorative Gear Arrangement that you'd normally get automatically from doing the FP in SM.

Furthermore, the bonus loot box that you're supposed to get for killing the remaining three mini-bosses after you've defeated Jos and Valk is not obtainable. The light bridges do not activate for the other three areas until after you've beaten Shae Vizla, at which point the bonus loot box is no longer available (i.e., even if you go back afterwards to kill the other mini-bosses, you get no bonus loot box.)

This issue therefore appears to be either some sort of bug, or the bonus loot box and the corresponding SH deco (Illumination Probe Crate) were removed (inadvertently, or otherwise).

Please address this. For many of us, the entire reason for going back to redo FPs is for SH decos. This is the second FP now where a rare deco is no longer available in the game because of an oversight. The other being the Manned Blaster Turret from Colicoid Wargames, though that's no longer available because loot drops were intentionally disabled in that FP since it wasn't level scaled, but the deco wasn't relocated elsewhere in the game.

EDIT: If you are unable or unwilling to resolve these issues, please offer these SH decos via the Cartel Market.
