Workers Stuck in Buildings / Workers Avoiding Work

Sometimes when workers work, they get stuck in roofs or in walls, and they just die off, their activity is always idle even if you give them work, is there a way to fix this or is it on check list of update?

I set workers to build a house, once they got to build the roof they stopped working and started idle.

Suggestion: Make it possible that we can grab the villagers or move them some way, my guard died because he went alone to fight the 4 undead.
