Reanimate cast bug

This spell is still being cast even if the target of the spell is absent, and such attempt lags the caster. In situations when you type "c reanimate bodypart target" target flees, you are still carrying the spell and getting yourself lagged. It happens very often. Please fix it so the spell will fail if there is no target with a reason "They aren't here", similar to other offensive spells. Yes, it will affect practicing this spell negatively, but it worth that. Thank you!
