Enemies don't regen resources between zone changes

[supermini]

It's possible for instance to enter a level, mana clash, leave to the previous level, and come back with the enemy on zero mana/vim. Enemies with paradox/equilibrium will have their resources steadily increase between stair hops, enemies with stamina will eventually run out, etc. Leaving a level should make a 'hard reset' on the enemies you left behind.
