[crossfire] Mover behavior?

[Kevin R. Bulgrien]

Given a mover...

Archetype mover_1, type Mover

name = mover
image = director.111
<invisible>
<forced movement>
movement speed = -0.2
direction = north
movement type = Walk

Is it expected that spells/prayers are affected by the movement
speed = 0.2?

It has the very odd effect of causing the magic to "stall" on
those spaces.  I think this is not the intended effect on the
map I see it on, but was not sure if it would be considered a
bug that a non-walking item was affected?

Opinions?
