hi, @Jarred_van_Vuuren. welcome to the discourse 🙂

does this only happen with building? does a save/load fix the problem?

if it is a custom building, could you post the building template?

glad you are enjoying the game

Okay so I can only send one image, and I don’t really know which one to  
pick?  
So if you need more to come to a solution I would gladly send more.

is this the only building that gives you problems?

the template we need is a .json file. it can be found in your stonehearth folder -\> saved\_objects folder -\> stonehearth folder -\> building\_templates folder

you should be able to upload more now that you’ve posted a bit

Yes and as well as when I try to build a building up against a mountain or  
wall,they just stop working I tried merging my other custom buildings with  
a mountain quite a few times but they just stop working and go back to idle  
mode?  
And those are two examples of the kind of buildings that I can’t build,  
most of my building usually contain corners as in those custom templates.  
Although if I build a simple square building everything seems to be in  
working order.
