[bug] Chalk lemmings sprites?

[mobius]

chalkboard sprites are still missing (I'm told its the shimmier that's missing); it defaults to normal lemmings when playing a Chalkboard themed level.

If someone needs to manually create a shimmier sprite for this set I can do that.

Shouldn't need manual sprites; they're recolors of the standard ones. The style just needs to be reconfigured to use the recoloring system.

EDIT: Fixed for next styles update.
