Could have left it there, perhaps, but I was just able to unequip it as usual. Fortunately, it was just behind the locked implant slot. But when I got in, I saw my Swiftboost was missing. I thought I had unequipped my Implants on the save I intended to use. so I just turned the Trait 7 into Trait 8 to turn double implants into Tank.

The traits are merely numbered, but it's basically 1-4 first row, 5-8 second row, etc. exit the editor, start the game, load the new/edited save. edit as you see fit, click done, hit alt+G to get ingame, hit escape to enter the menu and make a new save.

Into the command window in the lower right corner and hit enter, click Game/Persistent Player Position, press alt+G, hit escape to get into the main menu, load your save, hit alt+E, once in edit mode, press F3, type PLAYER and hit enter, hit F6 and find the TRAITS property. You need the Shocked editor (install via SS2tool), start it up, type 'yes, but this smells like breaking the save and maybe even the game, if you ask me.

Probably would have gotten back to Hydroponics faster from a fresh save though. MIGHT have been able to figure this on my own if I had enough time.
