Hi,  
I cannot seem to build in game. Affects both designing a custom building as well as building a pre-designed house.  
Please note the problem is in the design phase of a custom building: for example I cannot lay foundations when I use the design tool.

The code is listed below when I try and build a pre-designed house:

develop-2998 (x64)  
stonehearth/lib/build\_util.lua:542: assertion failed!

Hi,  
What predesigned house are you looking at? Is it a custom template you made yourself or something the game provided as a template? If it is a custom template, it’s possible that template has become corrupted somehow … (if so, please upload the template). If it is something that the game provided (like one of the ascendancy houses), please let me know which house.  
Thanks  
-Yang

Hi Yang,  
It affects both custom and game provided templates. When I try and select a template and place it down on the ground it just disappears and the code that I posted pops up. Also I cannot do anything on the design builder itself - it just disappears when I try and place it on the ground too.

Cheers

EDIT: I have figured out the problem.  
It seems that if I try to build the custom file first it just causes the whole build tool to fail. However it works fine if I just don’t try and build the custom template.  
I hadn’t realised this earlier and so always tried to build the custom first.
