a dog said bug: no surgery on 'was tame' animal

[Bobisme]

We had a Sloth who got brain damage, he had no movement so he stayed by the hospital, waiting for a brain implant.
He stayed there until, tameness reduced to 0%, he was wild but imobile.
We kept him on tame, they kept feeding him, finally we installed the new brain stimulator.

The doc arrived with the brain stimulator, gave anesthetic to the megasloth and everything went smoothly seemed a success but at the end of the procedure he walks away and there is no change, still brain damage, no crit failure still under anisthetic and a procedure that still waits to be done?
