My artist working on 2 sculptures?

[SimPuppet]

My artist seems to be working on one sculpture before finishing the last one he started?

Yeah, I have that all the time too.

I used to have that too. I started keeping to some simple rules and it never happens again.

Only build as much sculpting tables as you have artist. So if you have 3 artist, have 3 sculpting tables.
If they start working on a second sculpture, select it and press cancel.
