Yeah, it's been changed, they now heal the subject fully, take a larger amount of time doing so, and let you wander around instead of nailing you to the floor.
Yeah, I noticed I'm no longer glued in position, staring blankly at the bacta tank door.
But wow, ten hours?!
I guess I'll wait until they're down to much less than 50%, before using the tanks. Makes healing your NPCs much more of a crap shoot: pull them out early, and make sure they're safe, or get the mot out of them and run them closer to the "Oh, God, what did I just do?!" threshold.
"While being part of a medical action, neither you nor your target can move (exception: after applying a Bacta Patch, both you and your target can move)."
According to the medical rules. I should be able to move about after applying a bacta patch on my npc. But I cant.
