Proposal: Stay where you are! [Trivial]

I've been making a lot of proposals lately, I know. Things are pretty dull here. Anyway, under the current rule system, a player can go to the arena, make a challenge, have it accepted, then go to the lab and get surgery before the Doctor has had time t resolve the battle. A simple addition: to the end of the first paragraph of rule 14, add:

Specimens in a battle may not leave the arena until the battle has been resolved.
