Good news, ConcernedApe released a quick patch, to fix multiple bugs that were reported. And also he changed some things after hearing his fans.
If you have steam version, you can play with the latest fixes, by selecting the beta option.
My favorite change, is that you can build in (most of) grass areas of the new farms. I'm SO glad he did this, the new farms were too punishing in space, in comparison to the standard farm.
Not only in grass, if you're playing in the 'mining' farm, you can also construct things in the area where ores are generated, now!
If you play the beta, do a small favor to the epic dev, report any bug you find.
