Bug: Canceling building still takes 100% of the materials

[Hellaciouss]

As the title says, canceling a building, even if it hasn't begun building yet and the little guy is still walking towards it still takes 100% of the resources and does not give them back.

This really bothered me, as it wasn't pointed out in the beginning.

Canceling a building in progress should at least get you 75% of resources back.
