Hey, not sure if this has been addressed or not hadn't seen a post when searching. I've found a bug that has dropped me out of the game entirely on doing so. When you have a room ready to be picked up for the supplies it gives, if you build an extension onto it before picking it up it will pause for a second then drop you out to your home screen. The supplies showed up when I was already in the build screen and I just shrugged it off and tried to build anyways. Hope they can look into this while it's a minor bug that isn't entirely game breaking it would still be nice to have fixed for future updates.
