@speed bug when changing maps

[b]Issue:[/b]
Using [b]@speed 0[/b] causes invoking player to return to that walking speed when changing maps.

[b]How to replicate:[/b][list]
[*]Type [b]@speed 0[/b]
[*]Walk around to check speed
[*]Type [b]@speed 100[/b] or [b]@speed 150 [/b]to readjust to normal walking speed
[*]Type [b]@go <#>[/b] (replace <#> with a different @go map than your location)
[*]Walk around to check speed
[/list]
[b]Additional comments:[/b]
This might be for any intial [b]@speed[/b] adjustment, but I noticed it particularly when I used [b]0[/b]. Also, my [b]max_walk_speed[/b] setting in [b]conf/battle/player.conf[/b] is set to [b]1000[/b], which mimics Body Relocation when walking.
