The recall skill seems a bit bugged when it comes to mvs:

(Lvl 7 recalling from ashes of nowhere to arkham)
<86%hp 13%m 0%mv 1221tnl 10 PM outdoor> recall
City Hall

[Exits: east west]
     (Glowing) A torch flares brightly from the ground.
     A pile of brown canvas has been left on the ground.
     Someone's left a pair of boots on the ground.
     A plaque shines here, waiting to be read.
     A poster marked "Wanted-Information!"
     A pit for sacrifices is in front of the altar.
(White Aura) A healer is here selling his spells.

<86%hp 13%m -50%mv 1221tnl 11 PM indoor>

This is because you tried to recall with 0 or less moves. 
Rather than take half your current moves (which would have no
effect or even help), you pay half your normal maximum.  

I reduced the movement loss to 1/4 to cut down on resting
time, but the rest of the effect is intentional.
