I’ve looked into other similar topics, but didn’t find any with screenshots or proper steps, so here is mine.
I designed a custom building for my workshops, but edited how the roof would look (any roof editing would lead to this). The error that I get is in the first screenshot, along with what happens when I try to build them:
I found out that when the builders stopped building, the roof would act like a seperate “building”, where I could click and delete if I wanted, but it would leave the buildings as is. I also noticed that the Building Templates couldn’t load a picture of my custom building:
As a added question, is/when will there be a way to either cancel, dismantle, or simple delete a building? especially one that is incomplete or causing errors.
