Thanks for the update.

Gameplay stopping bug - Can't build upgrades for the mansion.
Using win64 version.  Erased old game, and extracted new game into old folder.

Try asking on the Discord channel. There is a Discord icon on the title page.

Thanks. Though I noticed the DL has been updated since I posted this.

I found out it was that the upgrade button disappears if you don't have the materials. It's not just greyed out, it's gone.
