Building error for custom templates

Hi All,

I seem to be having an issue where my people are not building any of my custom buildings. They are able to create the template buildings that are already there but when I create my own I get a message stating that they cannot build it and the error blocks will be highlighted in red, but there is never any red blocks. Has anyone else experienced this?

Can you please upload an example template or savegame showing the issue?


This is what I am getting no matter the template. The example template in the picture is a simple room with a roof and one door nothing else. I have tried even simpler buildings than this but none of them seem to work.

It’s hard to tell what the problem is because just recreating that from the picture and description works fine. As mentioned, a template or save would be ideal.
