First of all, love the game. It has quite a lot of issues, but thats where a Alpha is for.
Builded a bigger house, tried to do it for some time but then the builders just stop after a certain amount of time. This time they got the first 2 floors ready and then just decided to stop it. They have been doing nothing for the last three days. Is there any fix for this or am I doomed to wait for the next release?
