U260 - waiting times out for no reason while in were form
The initial report thought this was related to summoning help.  It's not.
moveloop would attempt to call you_were() even when you_were() would not
actually change your form.  Certainly there's a layering problem here, but
for now, just put in the same check peffects() uses to avoid calling
you_were() unnecessarily.
